I picked up my gun on Friday. I own an FNX45 as well. I'm extremely happy with the 45. I'm not very happy with the 10mm. I've been around firearms since I was in the service. I've loaded countless magazines .45, .357, .40, 10MM, 9mm etc. etc. I'm a licensed electrician, so I turn wire nuts for a living. My hands are not weak, and for the life of me, both magazines say 10 rounds. I cannot get more than 8 in each magazine. I also have to slam them into the gun so the magazine will lock in! Very disappointed.
