I have a 45 round one from DPMS works great, never had a jam.

likewise on the "no". i had a few over the years and most all of them would FTF around the 7 round mark (meaning that there were 31 rounds or so left).

Look at the mags made by Tripp Research. Friend of mine uses their 42 round mag, fully loaded, in his 3 Gun rifle and has never had an issue. The 52 round mag Tripp makes does not feed as well but he loves the 42 round one.

Wow $119! hmm, well im gonna look into the dpms and C products. chuwee81 I need you to do some more research for me on the c products 40 haha. If the dpms 45er is real good I might end up with that one even for $75

CMP,

You're just a little ways down the road from me in Haslett.

If you haven't heard of us, check it out. www.actshooters.com

Next competition is this Saturday. It's gonna be a cold one and I'll be home watching tv because I'm a puss. But feel free to drop by to watch and ask questions, everyone is cool and are more than happy to help out.

That'd be me.

The Tripp Research 42 Round Supermag (http://www.trippresearch.com/store/store_ar.html) works well and is built like a brick outhouse.

I've run the one I have at pretty much all of our local tactical rifle matches, as well as some 3Gun matches and it's functioned without fail.

It's spendy, but worth it.

30 ain't enough?

Whatcha plannin', anyway?

The 30 sticks out more than enough for me. In fact, I like the 20 much better.

40 and 50 round magazines can be quite handy for run 'n' gun 3gun stages. What are you, some kind of anti? :p

Thanks guys, well at first I will be using it for fun, but I would like to get into three gun shoots within the next year or so...Still need the three guns im gonna us though. I plan on my AR, beretta 92fs and a saiga 12 to start out with, what do you guys think about that? would that be fine to start with for 3 gun? Oh and HJ857 I might just have to go see that, thanks.

Yep, me too. I don't know but I've always assumed that many people don't realize how much you have to stick your head up in the air with a 30 round mag while prone.

saiga 12
I believe that will put you in open class. Be ready to run with the guys that have way too much money and all the cool toys. You might think about a pump or non external magazine shotgun. Justin runs a left handed Benelli M2 with a decent amount of work done to it specific for 3 Gun. He can tell you all about it. I want to shoot in He Man or Heavy Metal using my FAL, 1911 and 590. But if that is what you have, then rock what you got. And by all means have fun.

Justin

CMP, before you run out and buy some new guns to shoot 3Gun, I'd suggest attending at least one local match to see what other people are shooting, or if possible, shoot a match with borrowed gear, or the stuff you've already got.

Also, take a look at the rules at your local matches. There are regional differences, but Gus is correct about the Saiga moving you to Open Division. If you're just shooting for fun and to see how well you can do, and don't care about placement or division, that's perfectly fine.

If you've already got the guns, load up, head to a match, and give it a whirl. As the old saying goes, run what you brung.

But:

Ahhhh, yes, the same gamesmanship that brought us 30" shotgun barrels with tube mags to match on supposed defensive shotguns. I think they should require a prone stage with distant targets at EVERY rifle 3-gun, and we'll see how popular those 40+ ers suddenly become. :p :D

I know this has been explained to you before, but perhaps it wasn't presented simply enough, or you were incapable of using Google to suss the answer out for yourself. God forbid you actually attempt to attend a match.

http://www.thehighroad.org/attachment.php?attachmentid=29698&d=1128794076

Tactical Iron and Tactical Scope divisions generally limit shotgun capacity to nine rounds. In 2010, in America, that's a fairly common round capacity for home defense and "social" shotguns with barrel lengths considered acceptable for home defense.

Shotguns that are longer than this, or have a higher capacity, are generally being wielded by Open Class shooters. In some cases, Tactical Iron and Tactical Scope shooters will also have longer shotguns, but capacity is the same. Having the longer tube simply makes the loading regimen easier when one steps up to the line. Not that this is something that most self-appointed internet experts would grasp.

I think they should require a prone stage with distant targets at EVERY rifle 3-gun, and we'll see how popular those 40+ ers suddenly become.

At our Tactical Rifle matches, shots are from 10-425 yards, and prone positions have been built into every single stage that the Match Director or myself have devised. That doesn't change the fact that there are times when 40+ round magazines can be effectively utilized.

Not that I would know, or anything, because it's not like I'm in the habit of designing stages for these matches, attending them, and actually shooting my gear under those field conditions.

On top of this, I've yet to attend a Regional or National-level match in which prone rifle shooting wasn't an integral part of the rifle-centric stages.

http://www.thehighroad.org/attachment.php?attachmentid=29698&d=1128794076

Perhaps those who compete in 3Gun have discovered that there are indeed times when one can effectively prone out with these large magazines, or are opting to use them during stages that don't as heavily emphasize the prone position. Perhaps these competitors are actually willing to try out something new, and if it works, stick with it, even if the equipment looks goofy to someone who's never tried the game. Maybe, just maybe, these people aren't the total idiots you seem to think they are.

CMP,

I run both the ACTS comp and 3 gun in Brighton (Livingston Gun Club) and Port Huron (Blue Water Sportsmans Assoc). Rules are different at all three places. ACTS is two gun only, no shotgun and mags with greater than 30 round capacity are not allowed.

Brighton 3 gun allows full shotgun mags or drums if in open division, you can run tactical division if you download the mags to 9 rounds. You'll need to carry at least three mags and four is better. I don't recall that Port Huron makes any distinctions.

Rifle targets are rarely more than 125 yards in our area - we just don't have the space to shoot further. The vast majority of targets are between a couple yards and 60 yards.

Brighton and ACTS are pretty similar in how you negotiate any given stage. Port Huron is different, you shoot far more rounds and many more targets. They use the rifle in more of a DMR role so you tend to shoot reduced targets at distance. Port Huron puts a much greater emphasis on the handgun. ACTS is the most rifle intensive and I'd say that Brighton is the most fun.

I use exactly the weapon set up you describe, though my Saiga is pretty heavily modified (krebs sights, e-tac twister gas puck, gunfixer gas block, magwell, etc).

For any given stage you're best off if you can carry, at minimum, four AR mags, four Beretta mags (six is better if at Port Huron), and four Saiga mags. A really good holster for your sidearm, with absolute retention that you can draw out of fast is worth it's weight in gold.

Who is "they" - you? USPSA? One of the many regional 3-Gun/practical shooting organizations around the country and world?

Prescriptive statements such as yours miss the point that it is the match directors' and stage designers' job to challenge the shooter's versatility - and his equipment's versatility - as well as technical skill, while taking advantage of the assets he has available such as geography, range facilities, RO's, target, resources, etc.

Here's a few examples how I try to keep competitors "honest" with their rifles at my matches:

Me anti? Hardly. I'm just practical. I don't care for 3 feet of magazine sticking out, as I find such a thing heavy, bulky and cumbersome. But I don't give a rodent's rump if others want such a thing.

Same here.

I would rather have two 20 round mags then one 40 round for any day, place, or use.

Even a 30 round sticks down too far a lot of times.

Prone with a 40 round magazine feels odd, but isn't impossible...

I have yet to have a good experience with 40 round mags. Maybe Magpul needs to make them. :)

Justin
January 5, 2010, 06:02 PM
Most of them suck, but the Tripp has been solid for me.

That said, it is essentially a specialty piece of gear that is, admittedly, not completely essential. I don't run it at every match, but will pull it out of the range bag if it seems like it would be useful. For a rifle or 3Gun match, I'll typically take a single 40 round magazine, two or three 30 rounders, and a pair of 20's. The result is that I have more flexibility in how I can approach a stage.

Zak Smith
January 5, 2010, 06:04 PM
I just about always run 30's, good USGI's or PMAGs. I have a Nordic/PMAG 45 (?) round mag or two, and a bunch of PMAG 20's. I never end up using them. If the barricade is low enough I would need a 20, I'll just do a 45* angle or rollover prone.

I think the photo in post #42 is what I was referring to as to hard to get prone.

I think where some of the differences of opinion come from, may be whether you are talking about three gun matches, or trying to get very very low if someone is shooting back at you.

As I recall it was sometime in the early eighties when we were issued thirty round magazines. I really liked them until I shot prone and realized that I had to stick my head up to do it.

I would rather have two 20 round mags then one 40 round for any day, place, or use.

Even a 30 round sticks down too far a lot of times.I agree and use 20 rounders almost exclusively. I keep a few 30s; but ammo comes in 20rnd boxes, it weighs less, it gets in the way less, and is easy to use from prone.

The only magazine that I have heard good results from and is somewhat reasonably priced is the Sterling magazines designed for the AR-18. These have the AR-18 slot (due to the different mag catch design), but they also have the standard one for the AR-15 as well. These are fairly rare (only made for the Sterling AR-18s), so I would scour GunBroker, gun shows, and the internet to see what I could find. I have not used one and honestly don't care to due to the unwieldiness, but if you like it go for it.

Wow thanks guys, all the info is great. Well I can tell you guys I dont plan to go out and buy these guns for just three gun shoots...they are already on my list of guns to buy. Im not sure if I would want to be in open class, im gonna have to start watchin 3 gun shoots to know how things work. I guess im just gonna have to get the 590 I want and get good at loading on the go.

CMP
January 7, 2010, 03:01 AM
I just had a thought, they make things to block the mag release for california ak type guns right? Well if I where to have one of those and a 20rd drum on a saiga would that take it out of open because it no longer uses detachable mags or any other kind of speed loading device?

Justin
January 7, 2010, 03:09 AM
The capacity is certainly an issue, however, even with a downloaded gun the Saiga would still have an advantage over a more traditional shotgun because they're much, much faster to reload.

CMP
January 7, 2010, 02:50 PM
Well how about with an 8rd clip, I wasnt sure if there was a rule on the capacity I just heard about there being one on the clips becuase its consider a speed reloader

Justin
January 7, 2010, 04:00 PM
Yeah, that's the thing. To reload a Saiga, all you do is change magazines, which takes about two seconds. To reload a more traditional shotgun, you have to stuff the shells in the tube one at a time. I'm not terribly fast at it, but it takes me around four seconds to load four shells.

The disparity in mag-change times is enough of a game-changer to be something that it would outpace the use of the more traditional tube-fed guns, which is presumably one of the reasons they're mostly relegated to Open Class.

The original poster was asking about the magazines in the context of shooting 3Gun.

I've never been in the military, let alone been in any sort of combat, so I'm frankly not qualified to comment on the utility of such magazines under combat conditions.

Ah, my bad. He didn't state it off the bat, but later on in the thread:

Other than the larger dimensions meaning that the magazine will not fit comfortably in your mag pouches on your rattle, there is really no concern. If you only carried one, and that was the one in your rifle, carry on.

Justin
January 10, 2010, 01:41 AM
Agreed. I've tried running the big magazine in a Blade-Tech mag pouch, and it doesn't work well due to the weight of the magazine. After trying that a couple of times, I switched to using the magazine only if it's convenient to start the stage that way.

Shadow Man
January 10, 2010, 01:46 AM
Only way I could see it working would be with an AK-type pouch and an AR mag. But I haven't tried it, so I couldn't really say with any certainty...but I wouldn't want to carry one in a pouch on my rattle...been there, done that, t-shirt's in the laundry bag.
