Got a first production one. Add to it a mag-well and a amb thumb safety, it is my IPSC gun. The tool never fail on me, accurate and reliable. I am at the 20k rounds trought it, no part had need to be fix or change because of a break. The external extractor is ejecting the case 3 to 5 feet to my right. S&W always have external extractor on there semi, they got the needed experience to make it work.
Excellent gun overall.
