They are readily available and very inexpensive right now. I have modified them for a Taurus 99 by slightly enlarging the mag catch slot. I have also made them work in an Arex Zero 1 by cutting a new catch on the front of the mag tube. Has anyone used them in something else?

I have read they will work in a High Power with some judicial use of a Dremel tool. I might try that tonight.

I was waiting for someone to call me out on that. Factory Arex VS M9. All I had to do besides measure with calipers was to drill a hole and file the top of it.

Interesting.  I have around 30 or so of the older zipperback 226 mags. Never thought about modding a mag to fit the 226. I have a shit load of o2fs mags for my 2 92fs'. May sacrifice one to play with tomorrow.

Yeah with as many guns as they can be made to work with, kind of hard not to lay some back into storage just in case.  

I have a pile of them, and don’t even own a Beretta 92 currently!

PT 92/99 just involved making the slot a bit wider. I did a half dozen in probably 10 minutes and it shows as they are a little rough. They function fine though and you could go slow with a file if appearance bothers you.

For the most part, non-CZ double stack metal mags are derived from the the Hi power mag. So just stick it in while holding it tight and rack a couple dummy rounds through the pistol. If they feed fine, you just need to mod to fit the mag catch

I learned in Iraq 08’ that M9 and 226 mags are interchangeable and will work if you hold the mag up.  Same mag body design just different lockup

Later in Afghanistan did modify M9 mags for S&W Sigma and Titas machine pistols (yes select fire). Same cut works in both. First did the measuring thing but later just removed mag catch from pistol, inserted M9 mag and scribed where to cut

You can also cut new bottom notch for 92S pistols.  Tried the M9 to preB cz75 but no go. Did conversions M9 to Taurus 92 too

I have nothing to add other than those Checkmate M9-mags are made from some well hardened and heat treated steel.  I've used the baseplates for rehabbing HI-Power and older, pre-92F Beretta magazines for years since they're a perfect fit for both.

The springs on the earliest Checkmates (pre-2008ish) might leave a little to be desired, but they are durable, very reliable magazines.  The later Checkmates are fantastic magazines, especially when they reverted back to and mimicked the old USGI M9 mags as made by Mec-Gar under subcontract for Beretta.

Removing the mag catch and marking sounds a lot easier than what I’ve done historically. I will attempt to do so this weekend with one of my High-Powers

The body is probably the right length but a new slot would still need to be cut and the factory ones are available again for $30 a pop. But I doubt it’s a ocular enough platform that they will be around in the future.

I tried it with a High Power this evening: M9 mag fits snuggly in both my Inglis clones but the single mag I tried was quite tight in my Belgian Browning.I removed the mag catch on an Englis , marked the location, and drilled/cut the slot. It does lock into place on the Inglis clones but extends around an inch past the but of the pistol. Function was not nearly 100% and the slide does not lock back on the last round. It would however, lock on the 5th round with a loaded mag for some reason.

Overall, I would consider this a failure as the factory mags fit and function better and are readily available. Zombie Apocalypse and no other options? Sure but I won’t be modifying any more for my High Powers.
