I owned one for about a week or so. It sure seemed like a cool little pistol. I tried a few different loads in it and they all sucked. That light plastic frame coupled with such a short barrel works against the concept. Fireballs and lotsa muzzle rise convinced me quick that this pistol is good for nothing. I suppose if it was heavier, and the barrel a little longer...oh wait that'd make it a different gun. I sold it back to the guy I bought it from.
It worked but was no fun to shoot. I spose a light bullet load could be tailored to it but I didn't want to have to specialize for it if I didn't have too.
I'd keep looking. YMMV.
