I have one that I really like. The big dot is easy to pick up and the U notch rear is a good combo. It’s the lightest handgun I have and I carry it when I run.

While it may not be a target gun, I did okay with it in Steel Challenge and ICORE matches. I can hit my 8x10 plate pretty regularly at 50 yards. But it will remind you that sight alignment is still second to trigger pull. One day it’s so easy to shoot, the next it’ll humble you.

I’ve seen one that the “star” on the cylinder got chewed up but Smith fixed it and he hasn’t had any problems since.

The only negative I’ve had is the sun angle can cause the zero to shift. It lights up one side but any white globe sight can do that.
