Jaypee, thanks for the "heads up" on the CZ 75B mag interchange. The high cost per magazine has kept me from recommending these to customers. As for myself I see two problem areas-First, being a southpaw with no controls on the right side I'd have trouble adapting. second, even though I have size 11 hands, my fingers are average length, I as well as others have found the distance to the trigger face a bit long on CZ pistols and their clones.
