I have researched and really not sure of the answer. I have a CZ75D with a bunch of mags. I am thinking of getting the Bul Armory Cherokee Compact in 9mm. Will my CZ75D mags fit the Bul and vice versa? I'm trying to get my carry guns on one magazine so I don't have confusion when things get hokey. I did the same with my 38/357 revolvers so no matter what I grab to reload them will fit.
