Just wanted to add my 2 cents worth. First of all, I am not in any way associated with this business (or any other business on here for that matter). I bought one of these a few years ago. I also had a chance to try a none prohib Sig 228 top end on it. First of all, the pistol functioned flawlessly, and was a dream to shoot. Second, and most surprising, the Norinco top end was much more of a tac driver than the Sig top end! Norinco mags are fairly easy to come by. I have not tried any Sig mags in this gun, I just stick to the Norinco ones; although I did replace the mag springs with Wolff springs. The only disappointment is that the Sigg 228 .22 conversion does not fit on the Norinco NP34. Other than that, I would say buy it !! And quickly !!!
