As somewhat of a "flag waver" for Ruger .22 pistols, I witnessed two "going bad" as of late.
One, a slabside in stainless, had the rear sight shift in the dovetail, the rear sight pin worked loose, the front sight screw always needs tightened (loctite failed) and a severe case of leading within a few hundred rounds, enough to keyhole and nearly miss the target at 25 feet!
On the other, the trigger went limp, but not after sending it's last round down range upon dropping the slide/bolt!
Through my years of shooting .22 pistols and revolvers, many have came and went, but I still keep a Ruger or two, along with a S&W K-22.
I also like the Buckmark, having had several Brownings since the "Nomad" and "Challenger" series, but there are far less accessories on the market for them, if you are inclined to tinker.
