I have been running any standard 9 , Blazer , Win ZQ stuff Win Nato all has run fine , I have 3 mags for this gun , but was at a shop on Sat and saw Pro Mags for like 23 bucks for the full size just for the hell of it I bought one , tried it out worked well locked open , fir the mag well just right , I never buy them and only get fact mags for every thing but it worked great today , I read were they upgraded the the newer ones for Canik ?? but its just an extra tilll I find sum more worked good for now , I could put a Sig 226 mag spring in if I had to but will try iy for now .
