I got a S&W model 422 .22 target pistol used a few weeks ago. I e-mailed S&W for a manual but hadn't recieved it yet. I was going to wait to shoot it till I could figure out how to take it apart but didn't. Could anyone tell me how it comes apart? There is a slide thing on the top of the gun, I think it has something to do with it but so far I can't get it to slide. I haven't tried to force it though.
