If you do not want to tune your follower and want slide lock back do not buy these followers. Without tuning they may lock back with 1 round in the mag. This gives you plenty of room for adjustment to fit your particular equipment. If you do not want slide lock back just trim slide stop tab or Follower shelf to bypass Slide stop tab.

Gram's follower kit for P320

Review by Rick Oshea on 3/21/2020

I bought two of these and couldn't get one of them to allow the follower to go all the way down. I fiddled and fiddled to no avail.I finally cut one complete coil from the bottom of the spring and everything works great now. I still think they are worth the money, for the extra round, in competition.

works great for my PPQ Q5 mags

I had to grind off the tab for the slide stop but it works great. Easily two more rounds in a mag.
