Double double stack magazines anyone?

[aaaaa]

I wondered if there were triple stack magazines and a search brought up this curious gun which looks like the magazine is dual double stacks feeding into a single double stack.

First saw a schematic for that type of magazine in this firearm, but it's likely been tried out earlier...

The Kel-Tec CMR/PMR 30 round magazines and Kel-Tec CP33 33 round magazines are the same quad stack design. And they work quite well.

Here is a CP33 magazine.

I will see your CP33 magazine and add a 17 round extension.



P.S. The extension has worked flawlessly for me, if any one is wondering.

I have several of the 17 round extensions for my CP33 magazines and all work flawlessly. Now if only Kel-Tec or an aftermarket company would make a reliable 20 round extension for the CMR/PMR 30 magazines.

Surefire makes a 60 and 100 round quad stack magazines.

Has anyone tried the quad stack AK mags? Do they work without feed issues?

 

[Dave DeLaurant]

The one of these I first heard about was something the Finns tried, the "coffin magazine" for the Suomi SMG:



I gather it didn't prove as reliable as double-stack or drum magazines, probably due to internal friction. in the complicated feed column.

I don’t think those have the best reputation for reliability though. Anyone know if the AK ones work well?

This is what I assumed was the subject of this thread. It's tough enough to get single stack .22 mags to work, so this is amazing.

My only gripe with large capacity magazines is weight; they turn small, wieldy guns into much heavier ones. Really prefer the 20 round mags in a Scorpion, even compared to the 30s.

Not quite the same, but heres another obscure gem with a weird "multi-stack" magazine-


Llama Omni, basically two single stack mags welded together and funneling into a single-column feed.

Honestly, a quad stack AK mag seems like a solution in search of a problem.

Ian just did a review of a high-cap Makarov that used an interesting (but likely fragile) multi-piece magazine follower with two springs to achieve something along similar lines.

Although the magazine design looks goofy it actually works rather well. They don't last as much as a single stack magazine (but they do last a considerable amount of rounds) and finding springs for them is quite hard - the russians prefer to sell you a complete magazine at the according price... The modern commercial version is called Baikal MP442 and has a thumb magazine release (it's design is goofy as well) - it's not a bad pistol at all, but nothing special either.

IIRC, those Maks with the hybrid magazine will also accept and hold a single stack magazine. I’m not sure if I tried shooting with one back when I owned Makarovs though.
