ATI offers a 9mm magwell conversion to use glock mags.

I looked at one of those awhile back. The problem with them is that the magazine blocks usually lock into the mag well via the standard AR magazine release, and the block itself has a magazine release similar to the paddle release on an AK.

The problem with this is that if you're used to hitting the traditional magazine release on your AR and you do this while the block is in, you'll dump the magazine and the block on the ground. If you want to keep the same manual of arms on a 9mm conversion as on a regular AR, you're better off going with a dedicated lower or something like this magazine conversion which seems like a really clever idea.

The only thing I can think of that's a downside is that you lose out being able to use specialty magazines, and you're stuck with the PMAG form factor. This isn't really a big deal, though, especially if weighted against the disadvantages of a mag well block or the cost of a dedicated lower.

Olympic had a maghwell that used the AR mag release also. After the 3rd day there wasn't an issue. With the ATI unit the release is in front of the mag, IMO allowing possibly a quicker mag change.

Go over to calguns and pick up a bullet button mag release.

Go over to calguns and pick up a bullet button mag release.

If the point is to maintain commonality of manual of arms between a full size rifle and a 9mm trainer, then this makes zero sense.

Figured I would update. I received mine the other day but haven't shot them. They seem very well made and are slip right in, but I'm concerned the plastic ejector will be a problem long term.
