Thanks to those stirring me right direction 1st off. What fixed a cylinder that stuck closed, almost, took two hands to open, was a screw located directly under the firing pin hole, with cylinder open I adjusted the screw until I could once again, open/close cylinder with one hand. 2" snub nose, 5shot, non +P, approx. 30yrs old. Has a couple thousand rds through it, functions flawlessly. 4" groups at 7yds easily enough, standing, freehand. Not a S&W but very good gun for price, about $330's these day's, it's not a quoted price just a guess,
