Just picked up a couple steel Glock mags for the 43x. First off, if you have a shield arms mag release you will have to go back to stock to fit the Glock mags. I tried to seat a Glock mag, and it wouldn’t fit past the shield arms mag release. After swapping mag releases back to stock it works great. The front to back rocking I would get from S15 mags is gone. You do gain a little more length in the grip department, but not too different. I have yet to shoot them yet, but updates on reliability will come! So far very impressed with them. Hope this information is helpful!
