I had one with a 3MOA Millett red dot sight. It would tear out a ragged 50-shot 1" hole at 25 yards off the bench with Aquila Match Rifle ammo.

Trigger had a little creep, but you get what you pay for. After several hundred rounds mine began to slam fire occasionally. I sent it back to S&W and it came back fixed, no further problems.

I swapped it (and a good bit of boot) for a Model 41. The 22A was a pretty good little gun, but I just wanted something better.
