Nothing is broken in the two that I have. They function fine. The 650 has the .22LR cylinder and the 676 has the .22 mag cylinder.
I was thinking of taking them apart, to check for burrs, rough places, etc. Slick up the trigger pull?
The cylinder on the 650 will turn counter clockwise, with the hammer down. I was thinking of filing the cylinder stop, so that it engaged the cylinder slots, a tad more. Maybe I should just shoot them?
