KR,
I don't have the KZ-45 Compact, to dangerous to allow them here in CA you know, but I do have one of the first full size KZ-45's produced. I have put in excess of 10K rounds through it thus far. It needed to go back to Wilsons when I first received it for trigger work and to have the grip safety adjusted, but other then that it has not had a problem since. The combination of Kevlar/steel absorbs the recoil more like a Glock then an all steel 1911. The feel in the hand is exactly the same as a Glock 22's which means to say that it is blocker then a standard 1911 but not near uncomfortable or to big like a Para. The mags work well, tac reloads are easier then with a stock 1911 and having that extra round or two is nice.
All in all not a bad pistol for the money. The Compact would make a great carry piece. I would suggest opting for the the newer pryamid sights instead of the stock ones if I could get one but that is just personal preference. The stock night sights will work just fine.
Final opnion, probably a good pistol for the money. Will serve you well especially for a concealed carry piece. Might even buy one if they were allowed here.
Good shooting,
Dean
