Shot one this past weekend. It was brand new, and for the most part it worked great.
I was not familiar at all with the pistol the first time I handled it.
Loading the chamber on the first round usually jammed the action unless you used forward pressure to chamber the round. The spring wasn't strong enough to ram that cartridge home the first time. After I figured that out, the rest was gravy.
It ran great! No jams, and pretty accurate for a little .22 auto.
I have a complaint about the weight though. The gun was suprisingly small once I held it in my hand. The pictures always make it look near-full sized. It is small. That means it is a little light. It is a featherweight gun, and the trigger is a little stiff. I end up pulling the round more or less to the right.
All in all though, aside from the size and weight, it is a great little shooter! A Buckmark pistol it isn't, but it is fun.
