I shot 100 rounds with my new 10mm without a single hiccup.This gun has great accuracy,feel,sights,trigger and nice aggressive grips. :)
I have an RIA Tac II. It has also been flawless except it did not seem to like one 3rd party mag.
I was talking to someone that said the stock magazines are not that good and recommended a Wilson Combat mag.
The stock mag I got works fine in it, my Dan Wesson Razorback, and my Fusion Firearms long slide hunter.
I use wilson combat mags in mine, but I agree with Ganddog that stock mag also works fine
