Good to know! (not a cz, please forgive me) I got a new FN FNX. I had the same experience. Called FN, it's normal. He wanted a video to see how hard I was slamming the mag in before he could give a true opinion. At range like loading speeds, it operates normally, but if you get in a hurry, the gun knows and saves ya step. This being a strictly offensive weapon to me, I like it! For a range gun, or maybe even a carry pistol, this would be unacceptable to me....but I wont carry a gun without a manual safety and still think a 1911 is the best thing ever.....take it for what it's worth.
