Well, I have been to the range with this piece twice. The first trip was just a quick funtion check, and I didn't have time to wring it out, however I did try various ammo brands and bullet designs as well as other mags. It ate everything I gave it, even my real light SWC handloads that were brewed for the revolver. It shot well first visit, however I did have it lock open twice before the mag was empty. I didn't make note of which mag or mags did it. I actually don't see how the mag could do it however there is a slight difference in the angle of the lips from the original to my Wilson Combats and Mec-Gear. I'll check closer today with snap caps and see if I can find the issue.
Second trip was yesterday, and she shot great. I tried to duplicate the premature lock and I was only able to do it once by pressing upward like heck on the slide stop while shooting. It wasn't easy, so I doubt I did it by accident. Once again she ate all I fed her, with all different mags. Checking for accuracy this time I will have to say it's dead on.
I think I figured out why the previous owner might have traded it in. I have a
bad habit of what I call "shooting loose" when I am going fast. Meaning I tend to loosen up my left hand . I did some draw from concealed drills with multiple targets. I figured out that if you get loose with this little booger it will hit you right in the middle of your forehead with empties.

I didn't have a cap on (which is unusual) and I got clanged real well a couple times. I mean ...it leaves a mark! LOL I bet whoever owned it before couldn't keep from getting hit. If I didn't know how to stop it I wouldn't like it either. It hurts! LOL Hit me in the glasses a couple times too.
Lesson learned...don't loosen up. I love it, it will make a great training tool to keep me from getting loose when I shoot Steel Challenge.
All in all, great gun. ANybody who says 3" .45s aren't reliable haven't shot the right gun yet.
Carry safe and carry when and where you can. I'm just sayin'.
