What!!!!! Hmmmmmm..... Why won't my 7 round Bersa magazine fit in my 8 round Bersa? It will. The slide release on my 8 round Bersa hangs up on my 7 round Bersa magazine and won't push the latch back out of the way so it can go past and latch. Hmmmmmm..... I'll file or Dremel the edge so it has a bevel and see if that cures the problem. BA-BAM!!!! Problem solved. Now all my mags are interchangeable between my Bersas. Or you could just push the magazine release button in while inserting the magazine. The world is full of Bersas so I thought I'd throw this little gem out there. Don't bevel the latch, just bevel the magazine.
