has anyone tried the 45 round magazine from dpms? they have a pretty good reputation and i can't imagine they'd sell something that didn't function well but $90 is quite a bit to spend on an experiment. any input would be appreciated.

You can get 4 30 rd USGI that do work for less.
Too long and heavy to carry.

roger that but i was thinking of getting one for my home defense rifle provided others have had good experiences with them. if something goes "thug" in the night, i'm not grabbing extra mags, just the rifle and although thirty really should be enough an extra fifteen would be nice.

I haven't tried it but here's my $0.02:
Stick with either a USGI 20 or 30 round mag for your HD rifle. If you feel you might need a reload, add either a Redi-Mag or a buttstock pouch to your rifle. Either of these is a good idea anyway, since many malfs in semiautos are magazine related. With a spare, you can swap it out if the primary goes TU.

Using that flawed logic, one would hope that you'd spring for a Beta-C mag, then you'd have 70 more rounds, should something go "thug" in the night.:p

rockstar, i KNOW the beta mags are unreliable.
mr. inquisitor, that's the logic that anti's use to argue we don't need more than ten round magazines or that we don't need guns at all. by that logic, i don't even need a magazine. after all, i'm just going to down "a single home invader" with a single shot between the running lights, right? i'm not planning on having to shoot anyone. i would like to be prepared for as much as possible. i'm not planning on having a fire in my home but i bought the largest extinguisher i could afford in addition to several small ones.
i'm not entirely sure why "the high road" exhibits this haughty smugness from time to time. if a 45 round magazine functioned well, what would be the problem? sure, you can't get the rifle as close to the ground in the prone position. i don't see myself taking up a prone position in my civilian life outside of massive civil unrest, in which case i'd probably grab a few extra mags anyway. sure it would be heavier, but it'd be lighter than two thirty round mags. so what's the problem?

obviously not. but i'd like to have as much ammunition reliably available as possible.
i'm gonna go out on a limb here but i'm guessing your home defense weapon holds more than one round, right?
i don't get it. thirty rounds is perfectly reasonable and no one assumes i'm going to shoot a single assailant thirty times (or miss thirty times) but i mention a 45 round magazine and suddenly it's overkill, i'm rambo and you guys start sounding like chucky schumer.

As a cop I can say no you won't. Heck it could be a bad shoot and you would probably get off. We had a precher shoot two scumbags in the back as they were running away he got aquited.
Now in reality do you need 45 rounds no. But if you hosed someone in a good shoot your not going to prison. Its all in the articulation.

understand that i am fully aware that 30 rounds is probably way more than i need. heck, odds are pretty good that i will never have to discharge a firearm at a human being and i pray that i won't. i do, however want to be prepared for any contigency and i just wanted to know if anyone had any experience with the dpms magazine. i suspect that it isn't as reliable as the 30 round mags i currently use but if it were reliable i wouldn't mind having an extra 15 rounds. i did not post this thread in strategies and tactics. i am not asking about whether you think i NEED a 45 round magazine. i'm asking if someone else has purchased one.
not that it's germane to the issue at hand but my hd rifle is also my shtf rifle. i want it to be as versatile and immediately effective as possible.

AR15 mags are the weakness of the system its not good to experment. In general mags with more than 30 rounds in most assault rifle mags don't work well. The problem is the spring tension has to be high to feed all those rounds making the first 5 to 10 rounds from the mag very difficult for the bolt to strip. Stick with USGI mags or HK mags. Thermolds are ok too.

Okay, I have to know. What laws are out there that dictate that you can only use a limited number of rounds for home defense before you cross the limit and have to do prison time for going over the limit? What law says planning to need 45 rounds for an intruder will cause you to go to prison?
You should consider reevaluating the bases for your statement. Three are no laws that dictate how many rounds you can use. Either you have the right to use lethal force, or you do not. If you do, then things like round count are immaterial.
chopinbloc said if something goes "thug" in the night, i'm not grabbing extra mags, just the rifle and although thirty really should be enough an extra fifteen would be nice.
Okay, so why aren't you grabbing extra mags? If you hear a "thug" in the night, why would you go to investigate and not be adequately prepared?
Interesting about the Beta mags being unreliable. I have several and they have all been great. I don't use them for home defense, however, because they are overly bulky. Others would probably find that the weight issue is also a problem.

Are the 45-rounders made to mil specs, or are they made for the civilian market only? If the latter, I'd probably stick to 30's, but you could always get one and use it as your "range magazine" until you have enough rounds through it to be confident in its reliability.
Do be aware that the rifle won't be quite as handy with the 45 in it. I have a few 30's and a 40 for my SAR-1 (AK lookalike in 7.62x39), but my main HD magazine is a 20 because it makes the rifle a lot more portable. If I were in a "SHTF" HD situation, I'd probably grab a 30 or 40, though...
I do agree that having a 45-round magazine in the rifle won't make a bit of difference in determining whether a SD shooting is justified or not. And there's no rule that says you have to actually use every round in the magazine...

I have 2 - 40 round mags made by USA Magazine I think. I haven't seen that brand around in the last couple of years. They both work very reliably in my Armalite. They certainly work better than some 20 and 30 rounders I have wasted money on. They are aluminum, not plastic.
I don't think one 40 round mag makes my rifle less handy. However, I tried a mag-cinch with them and two 40 rounders seemed to make the weight seem a lot more.
Someone recommended a company to buy 30 round mags from. I think it was Eagle something. I have had good luck with their 30 rounders and they are cheap.

It connects two 20 round mags, giving you the additional rounds and the reliability of a second mag should the first one jam. For a lot less $. I have them on all my Colt GI mags and it works well for me. If you jammed on #2 of a 45 rounder, you'd be better off with a bolt gun. If you jammed on #2 of a 5 rounder, you'd be better off with a bolt gun.

Some is good
More is better
Too much is just right
If the freaking 45 round mags work there's no more reason to jump the guy than someone asking about using 30s when the 20s exist. I don't see people pound on folks with AK drums either.
The point you really need to consider is that there's a huge body of information about what good 30 round mags there are vs those that aren't reliable. I can't advise anyone picking any less than proven equipment for SD. Buy one and run 500 rounds through it and then decide. If it hiccups even once dump it or keep it as a novelty.

I think you guys are misunderstanding me.
First off, I live in illinois, not Alaska, and certainly not Texas, so one of the first things on my mind when it comes to a home invasion (besides the obvious) is what is going to happen after the dust has settled.
More than likely, in a very anti-self defense enviornment, something will come up like, "Well, Mr. Inquisitor, why did you need an assualt rifle...an assualt rifle with 45 deadly rounds of military ammunition"!
Unfortunately, this sort of arguement is pretty rediculous, as it works for everything about a .17 bb, but what I am trying to say is that you need to consider what will come after a home invasion - you're not really "protecting yourself" if you defend yourself, but then put yourself in a comprimising situation to be tossed into prison for some type of murder/manslaughter.

You made a very absolute statement which is never a good thing to do. Political enviroments are different everywhere. In your situation the best bet would be to use the most PC gun you could. But even there if you had a good attorney you would not be going to jail so long as it was a good shoot.

November 10, 2005, 11:47 PM
okay, i live in az. fact is i could probably chase a home invader down the street laying rounds into his back as he fled and get away with it. that's not what i intend. if someone breaks into the house while i'm sleeping (unlikely, burglars prefer daytime and tend to shy away from second story apartments) i will grab the rifle (it's within reach) and push my beloved out of the bed. she will call 911 and i will keep the muzzle trained on the bedroom door. there are innumerable scenarios that can and do happen to decent folks and i'd like to be prepared for anything i can be prepared for. on the subject of spare mags, i have a buttstock magazine pouch on the rifle but found that two thirty rounders clamped together compromises the weight and balance of the rifle too much. if i did purchase one of the new dpms mags i would extensively function test it before i considered it adequate for defense. the magazine in question is an aluminum body made from two thirty round gi mags with a green follower. it looks like a decent product. dpms has a good reputation but i'm not spending $90 on it unless someone else has had good results.
on beta mags, i appologize if i overstated by saying that i KNOW them to be unreliable. what i mean is that i've heard very mixed reviews on them which to me translates as unreliable. i have never heard someone complain about the overall reliability of gi mags and i have personal experience that affirms my faith in them.
bottom line: i'll probably stick with one thirty rounder in the weapon and one on the buttstock as this works well and it doesn't cost me another $90. i appreciate the input and if anyone out there has actually tried one, i'd still like to hear about it 'cause it's still a fun idea.

I'm amazed that people would condemn a mag that may work with more ammo by saying you won't need it.....sounds like the anti-gun crowd.
If it works, run it. The 45 round mag is decent in 3 gun as you don't have all the weight of a Beta C and have a significant advantage over the standard 30. All Mags are unreliable until tested in your rifle. If I can avoid a mag change in a bad situation ...I WILL.
If you sleep better with more rounds than 30 buy it or the Beta C. Test it out and then run it if she works.

Sounds good to me! I personally dont mind people getting shot in the back as long as the right people are getting shot.
If you absolutely positively cannot shoot him lots of times, I recommend using a 12 gauge. A single hit with 00 Buck should turn someone into pasta sauce.

all right, let's back up. i didn't say that, double naught spy said it. i specifically said that i'd be holing up in my bedroom if someone broke in. realistically, if i am pretty sure someone is in the house, i'm gonna hide and call 911. if i hear something funny i'm gonna check it out myself. we live in a second story apartment in a three story building, right in the middle of the building. if i called the cops over every funny noise, they would stop coming and maybe haul me off to a padded room. i have had a very little bit of training in room clearing. enough to know the bare bones of it and enough to know that it is without a doubt a team sport.

Its nothing to do with technology. With the current magazine designs (box mags not drums.) the greater the number of rounds the greater the spring pressure is required. The greater your feeding problems for the first few rounds. If they were worth a damn you would see the pros using them but they don't.

Okay, let me try to clear up a couple of misconceptions here. The DPMS 45-round magazine was designed from the ground up as a competition accessory. It's intended for 3-gun and practical rifle shooters who want more capacity, to prevent having to reload during a stage. It's made from two GI 30-round magazines, sawn apart, welded, and refinished.
355sigfan is completely wrong when he says that the greater spring pressure in the 45-round magazine will cause feeding problems. The 40- and 45-round magazines do use a longer and stronger magazine spring - the increased spring force is counteracted by the increased weight of the cartridge stack. The amount of force holding the first few rounds into the magazine is about the same as in a standard USGI 30-rounder.
The DPMS magazine is brand new - mine haven't arrived yet. But the quality of the one I've seen is excellent, and I'm willing to spend the money to give it a try - particularly because DPMS function-tests each one before sending it out.
I don't think that I would use a 45-round magazine for defense, just from a handiness standpoint. My house gun is set up much like chopinbloc's - one 30 in the gun, one 30 in a buttstock pouch, and I see no particular reason to change it. But you never know.

Sorry bud time for you to learn some basics about magazine design. Whenever the magazine capacity is increased the spring pressure foes up. Extreemly high cap mags are plagued with problems due to either too much pressure on the first few rounds or none enough to get the last few to feed. There is a reason their a competition only mag (ie if you used them in the real world it would get you killed.)
As for DPMS's warranty product your going to need it. We are issued their rifles and as an Armorer their a big headach. Gas tube retaining pins falling out J springs breaking. Ext. Stick with quality mil spec parts and guns.

Sorry bud time for you to learn some basics about magazine design. Yes, I'm sure that you have plenty to teach me.
Whenever the magazine capacity is increased the spring pressure foes up. You know, I think I recall saying that in my last post, right before the part where I said that the increased spring weight is balanced out by the increased weight of the cartridge stack. Perhaps a bit of re-reading is in order?
Extreemly high cap mags are plagued with problems due to either too much pressure on the first few rounds or none enough to get the last few to feed. Funny that the Sterling 40-round magazines don't have this problem. Neither do the 50-round box magazines used in the Galil. Perhaps you meant to include a "some" in front of that "Extreemly??" Those blanket statements can be a bitch.
Magazine design involves selecting a spring weight, compressed spring length, and relaxed spring length (among other things) that matches up with the weight of the cartridge stack and the length of the magazine. It ain't rocket science.
There is a reason their a competition only mag (ie if you used them in the real world it would get you killed.) And you've used a DPMS 45-round magazine in how many real-world engagements? None? Have you ever used a DPMS 45-rounder at all? No? Have you ever seen one used? Have you ever seen one at all? Then you really don't have a clue what you are talking about, do you?

Also, don't forget the other extremely high capacity magazine the Russians designed. Those crazy Russians.

You know, that high cap AK mag kinda grows on you... Of course if I tried to carry it around loaded I might change my tune. :)

Yes, I'm sure that you have plenty to teach me.
You know, I think I recall saying that in my last post, right before the part where I said that the increased spring weight is balanced out by the increased weight of the cartridge stack. Perhaps a bit of re-reading is in order?
Funny that the Sterling 40-round magazines don't have this problem. Neither do the 50-round box magazines used in the Galil. Perhaps you meant to include a "some" in front of that "Extreemly??" Those blanket statements can be a bitch.
Magazine design involves selecting a spring weight, compressed spring length, and relaxed spring length (among other things) that matches up with the weight of the cartridge stack and the length of the magazine. It ain't rocket science.
And you've used a DPMS 45-round magazine in how many real-world engagements? None? Have you ever used a DPMS 45-rounder at all? No? Have you ever seen one used? Have you ever seen one at all? Then you really don't have a clue what you are talking about, do you?

The only one without a clue is you. 50 round Galil mags have had problems. I have plenty seen plenty jam on the class three firing line. I have not tried the DPMS mags but I have seen plenty of 40 round and up mags choke from other makers. DPMS is not a great company so I expect no better from them.
And magazine design has some very specifiic tolerances and while its not rocket science it still takes someone with more of a clue than either one of us to design. But hey its your money spend it as you see fit.

I truly don't know why I bother...
Galil 50s. (I don't believe that you've seen more than a bare few magazine-related failures with Galil 50s.)
Sterling 40s.
Thermold 30/45s.
Direct-spring drum mags like the Firepower and MWG. Or did you think that coiling the cartridge stack into a circle makes a difference?
Even the Beta has, for all intents and purposes, two interlinked 50-round stacks.
You are wrong, on many different points, and all the stupid little cliches in the world aren't going to make you any less so.
I'm done with this. Until my DPMS 45s show up. Just for you, Pat, I'll take some video of me running a few magazines through my carbine, then sit back and wait for the posted retraction and apology. :D

WIth all due respect I will be the first to admit I am wrong but I don't think I will be proven wrong on this issue. I have seen too many extreemly high cap mags crap out. I also don't appreciate your personal attack which is a violation of the rules on this fourm. If we can't express our opinion with people taking cheap shots then this is not a good fourm to be on. I don't think its too much to ask that you stick to the topic rbernie and stay away from personal attacks.

Strange. I've seen probably more standard capacity mags crap out than hi-caps. Of course there are many more standard cap mags out there, but it just goes to show that any mag can fail. I certainly wouldn't limit myself to standard caps simply because of a fear of future failure with a hi-cap.

I will stick to proven items. I waited on the HK mags until the reports came back good.

First off everyone needs to take a breath and try not to take disagreements personally. Before this thread gets shut down I will put my 2 cents in one more time. I agree with 355sigfan to some degree. There are many magazines that have been designed for over 30 rounds that have malfunctioned consistently when loaded to over 30 rounds, and there can be a problem with extremely high capacity magazines due to spring tension. The Sten gun magazines and I believe the MP40 magazines had this problem, not to mention the many aftermarket AR-15 magazines. I also agree with Chris Rhines, there have been numerous designs that have succeeded in creating a magazine that holds over 30 rounds. The Steyr Hbar, RPK, HK33, amongst some that have already been mentioned can reliably feed while holding more than 30 rounds. The question that needs to be asked then is what do these magazines do to mitigate feeding problems that others do not, and has DPMS done this in their new magazines?

Pat - in this thread, you replied to Chris with: Sorry bud time for you to learn some basics about magazine design. And:The only one without a clue is you. And finally, when Chris indicated that he'd "sit back and wait for the posted retraction and apology", I chimed in with:I don't think that Pat knows that tune. To which you reply with: I don't think its too much to ask that you stick to the topic rbernie and stay away from personal attacks. Take a deep breath and read your own words. My response was not an attack - it was a statement of fact based upon your presentation. If you don't like the conclusion that I've reached, then maybe you should look at how you interact with the members of the board.
