I've had mine now for over a month. Very pleased. Prices have dropped substantially, I paid $279.
Mine is very accurate and reliable. Seems to prefer the cheap stuff, Wildcat & Blazer seem to be the best so far. It also shoots Stingers extremely well, something that my Mark II won't do.
What has really impressed me is how clean the bore stays. Last time out I shot over 300 rounds and seven brands of ammo, plated and plain lead, and there was no fouling in the chamber or barrel. I just cleaned the breach area and oiled it up and it's ready to go.
Two thumbs up.
