So My form 4 finally went pending.. Hopefully in the next couple weeks it gets approved. The can is a .45, but the 9mm adaptor (YHM Cobra M2) will fit a threaded Tac Sol .22 barrel. The can has a booster, and I realize it wouldn't be .22 can quiet, but how would that work on a .22 pistol? anyone done it? Tac sol. is a fixed barrel, so would the pressures of a .22 round even move the spring? I don't want to screw up the can or the threads on the weapon, but it would be nice to use it a little until I get a .22 can. Who's done it? How Loud with say standard velocity run of the mill stuff?
