I had one when they first came out. I liked it a lot and shot it in matches, it was accurate.
I had to send it in for repair for 2-issues. I was experiencing intermittent, light primer strikes with the first round from the mag., which I thought might have been caused by the firing pin safety.
Also, both of the Wilson mags started causing a malfunction where the slide would lock open when empty on the take down notch and not the slide stop notch.
S&W Customer Service had it repaired and back to me in short order. It had no issues after that.
