I took my new BG2.0 to the range yesterday. 250 rounds starting with old WWB ammo (120 rounds), the Tula steel cased (100 rounds), then 30 rounds of assorted SD ammo that I have sitting around, PMC Starfire, Sig V Crown, and my carry ammo, 99 grain Federal HST. Zero failures with one exception that I was mildly confused as to cause. In the middle of the steel cased ammo the RO asked us to finish up so he could go cold. It was pouring down rain (we were under cover but it was Florida rain so the gun was wet, I was wet, and the gun is small with strong springs) so I dropped the mag and went to clear it and I kept slipping on the wet slide so I just shot the last round with no mag and strong arm only. I didn't limp wrist it but the gun fired and the empty case stovepiped. That was the only issue.
Very accurate gun. Very soft shooting. Sights (rear) visibly not centered as reported many times. Shot left. I drifted it when I got home to visibly centered but I can tell you those tiny sights are pressed in by a hydraulic monkey. It took a lot of effort with a brass punch and hammer to break it free. S&W should do better from the factory, not too much to ask for centered sights.
Love this gun. Easy to shoot, easy to shoot fast, easy to shoot accurate. I like the sights. I won't swap them. I did buy the Talon grip spider stuff for the slide serrations and top of slide. It is a tiny slide with a strong recoil spring. The wet conditions really hammered that fact home. Some abrasive tape on the slide can't hurt.
It was stiffly sprung out of the box and the manual safety was very tight and hard to actuate. I sat in front of the TV last week and cycled it a couple hundred times probably and it has settled in quite nicely. Easy to swipe off with my thumb during a draw and about zero chance of accidentally applying it. I like the safety.
