dpms 45 round magazine

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.

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.

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.

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.

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.

In all honesty you should not be trying to clear your home. Thats a job for a swat team. There is no safe way to clear a building by yourself.

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.

I don't think their trying to sound like the anti-gun crowd. Just USGI snobs :p
 
Okay, so does anyone know how reliable the dpms 45 round magazines are? Is there anyone who has had prior experience with them?

If they work, I might also want to get a couple for my AR. (Not that it matters, but I'm interested from a 3-gun type standpoint.)
 
and there haven't been any new products in the last fifty years that are worth a damn. and if you can't do it with one round you're a lousy shot and you're going to jail and you're probably a communist, too.

look: there are plenty of crappy 30 round magazines out there and i own forty round magazines for both my mini14 and my sar1 (came with the rifles) they work flawlessly. the 75 round drum for the sar1 works flawlessly as well. most of the time a new product like this is a gimmick and is not worth the time or money. sometimes they work. that's why i started the thread - to find out if anyone has actually used one. we all know the gun industry is full of gimmicky products that don't work. if it was made by some company with the words extreme and tactical in its name i wouldn't even have asked but dpms has a decent reputation and i haven't heard of complaints about any of their other products.

now, has anyone USED one of these magazines?

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.

Like we have been saying extreemly high cap mags are not reliable period. That simple enough.

That is true most of the times, but the Russians have a design that might have some merit.

well, the forty round mag in my mini14 works just fine and it's the same caliber and a similar design. i don't know if the dpms magazine works but i'd like to hear from someone who does know.

Dont say this if you dont mean it.

The 30 round magazine is a known quanity, there is nearly 40 years of history showing that it works well, people arent generally willing invest 5 times the cost of a known-working magazine for one that offers so few advantages.
 
mr. yeager, we all know that gi thirty rounders work and there's gimmicky stuff out there. it's just funny that everyone wants to chime in about how they KNOW the product won't work when they haven't tried it. not only do they KNOW it won't work, they KNOW i'll go to jail if i let one get near my rifle and they're pretty sure i'm a whacked out psycho mall ninja and i must just want to hose somebody 45 times just because i asked if someone had actually tried the magazine.

whatever. this threads been going for a few days and i'm guessing that, like me, no one else wanted to spend the money on a potential piece of crap. i give up.

You don't have to try every piece of crap to know its probably a piece of crap.

Sigh.

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.

Give it a try. If it doesn't work, DPMS has an excellent warranty program. You really have nothing to lose.

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.

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?

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. :)

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.
