Speaking of Tommy Campbell, it would be curious to know just (aprox) how many rounds he fired in the custom .45 S&W built out of two Mod 52's. Back in the mid 80's when he came several times to the Masters Int Shooting Championship, (which he helped design), that pistol was the smoothest operating I ever saw, and he consumed copious quantities of ammo. He always had the spare magazines right side up in his mag pouch's. Fastest speed load ever. He used to say his occupation was a creater of once fired brass.
