Look at the Colt AR15 9mm magazine - now look at the UZI magazine - only difference is the catch location - now look at the Beretta Model 1938 magazine - yep same mag again.
Take a look at that P38 magazine you stuffed into that Astra Model 600 - now look at a SIG 225 magazine, the 225 is the same just a little longer with catch location on the side.
Lots of makers magazines can be made from other makers - Beretta M9 mag's can be modified to fit Taurus 92.
