I can understand not like the mag on the CZ527.
I can't wrap my head around a beef with a "backwards" safety? Think of it like a hammer. You pull a hammer to the rear; just pull the safety to the rear lol.
Its because of muscle memory. Most safeties are push forward to fire. Shotguns have always been that way and until now, with CZ, most rifles. The more natural it is to operate when you are hunting, the better. Why CZ wanted to make them operate backwards is strange.
