Need to file bottom of mag

by

Yes, it holds 10 rounds. I got 3 of the +4 mag extensions for three gen 3 mags and all of them, the follower hung up on the bottom of the Glock mag. The part of the follower that holds the slide back on the last round is what hangs up on the bottom of the mag. That is the place on the bottom of the mag you need to file smooth. If you have that problem, I fixed it in 3 minutes with a small file. It is the Glock mag or the follower problem and not the +4 mag extension’s design. That is why it gets 5+ stars!!! 10 rounds of Awesome! When you put it together, put the back of the mag in first. It will make sense when you are doing it.

handy items for range mags not for edc

by

i have several of these for my glock 43 range mags. they do hold ten rounds but won't go in gun with slide closed unless you only load 9 rounds. i like them though for range time to avoid reloading so much.
