My CZ Shadow 2 has digested everything I fed it....maybe 2,000 rounds. It rejected some really badly overcrimped first setup on my RCBS single stage. They were bulging. Glock 17 thought they were candy. Smith said maybe. So, NOT to be a Mil-Spec Gun, it performs flawlessly. I had one other failure where I did not properly seat a primer in the first set up of my DILLON 1050. I also have had more complaints from my SA 9mm Range Officer. It’s chamber is a bit tighter....needs to go bang more.
A buddy likes Mil-Spec or Mil-Surplus Guns. Basically, he shoots s CZ75 that he souped up a bit better than most others. When new, it was better, I think, out of the box than his knock off Desert Eagle “CZ clone”. I shot that one... I also shot a nice Beretta 92 fs(?) he had with all the bells and whistles, we both shot the DE better...
He won’t be disappointed until he shoots it a while. I was disgusted with my PC SW MP 5L and my Glock 17. I shot a CZ75 shorter barrel gun at the range when a member noticed my interest (was the RSO). I put 10 down range. Shot the buddy’s DE and Beretta the next day...and bought the Shadow 2 the next Wednesday.
my experience....others will differ...
