$500, 12 oz, single shot .45, about 3.5"x2.5". I'd take that over a mini revolver, any day. My 70 gr prefrag, rechamber the gun to 460 Rolwand, would probably still get 2000 fps, still break into 3 segments at impact. 640 ft lbs,not 60 ft lbs from a .22lr mini revolver, or 120 ft lbs from a mini that's in .22 mag rimfire.
