The revolver is pretty much new. I've put about 100 rounds of wally world target 44 magnums into it. Went shooting today and everything was smooth for about 18 shots. After the 18th shot I couldn't open the cylinder to unload the brass. The cylinder release lever comes forward but there's a dead stop on the cylinder. I had to hit the other side of the cylinder really hard with the bottom of my fist to get the cylinder open. I closed the cylinder (no problem closing) and again, lots of force to open up the cylinder. Forcing cone to cylinder gap present. Gun will cycle to next shot smoothly. Just cant open without hammering the cylinder. What do you guys think is wrong with my gun? I guess I'll call SW tomorrow if i cant figure it out. Thanks.
