So i picked up another sig this weekend at the fun show, a p250c w/NS, 9mm and 2 extra mags, p250 was about $420 out the door and the mags were $20 per, not counting the one it came with. My question is about the mags. They have witness holes for 16, but wont really hold 16 rounds. I can really PUSH that 16th round in, but then the mag wont go in. Is this just a break in issue or is the 16 witness hole a lie?
