Pearce plus 1 - Pearce Grip Glock 43 1-Round Magazine Extension w/Grip

This does not work on 33388-02 glock 43 magazines. It works on Glock 43 33388-01 magazines. Your cannot get the plus one in there for the -02 mags. Check the back of your mags. The mag I bought from optics planet was the 01 on the back and it worked for that one. I was able to get 7 rounds in. But on the 02 I could not get 7. I checked peace grips and it had the information. Wish optics’s planet had that in the description.
