magfull

Good point. It's a new purchase and mags haven't reached their 'set' yet. Thank you.

Thanks again.

Thanks. That's what I originally thought but the mags from the second G43 don't work in the first G43 either. Also this was an original Glock 6 round mag so adding the +1 floor plate has actually extended the length of the mag spring (lessing the upward pressure). I will take your suggestion and swap springs just in case the spring is jammed inside. Thanks again.

General Question: I have a Glock 43 with a +1 mag floor plate. After loading 7 rounds and fully seating the mag in the mag well, the slide cannot be retracted to chamber the top round. The slide moves back 3/4 of an inch and stops. I have another G43 with several factory mags with the same +1 floor plate - no issues retracting the slide on the second G43. The mags from the second G43 also fail to feed in the first G 43. However, the first round WILL extract if the slide stop is locked to the rear and released after the Full mag is inserted. Except for the +1 mag floor plate, everything is factory and no modifications of any kind have been performed on either G43. BTW - Six round mag feeds just fine. Thanks for any valid suggestions.
