My only experience with them was 20 years ago when a buddy who worked at the Gold Vault handed me his brand spankin' new 337 Air Lite. I had been watching him and another friend shooting it with mid range wadcutters. He handed it to me stoked with some of his "work ammo."

It went, "Bang" and I went, "Ow" (much their mirth and merriment) as the triggerguard smacked my knuckle. I fired the rest of cylinder full and got a nice group. The thing was hateful with the little grips and that Treasury ammo.
