LOL! I hesitated to tell my story, but here it goes...

Back in the 70's, I'd buy used S&W 4" revolvers, cut the barrel, drill and tap it, and install a shot gun gold bead for the front sight. They were a hot item back when I lived in Detroit! Back then, people thought they would blow up, or it was illegal to do so.

Note: My apologies to all collectors out there.
