From what i saw on the mag release, a big part of it is the design: if you look at it, the pad where you press is towards the top. if you dont shift your grip, you're putting downward pressure on the release, pushing it against the frame instead of straight in. slide release was horrible to actuate, but will probably get better over time. i didn't see anything fit and finish wise that was bad. but the trigger was definitely not as good as i thought it would be. the Canik's trigger is better out of the box. and a Glock trigger is better with $30 worth of parts.
