My Model 37 Air Weight from Smith & Wesson is about 30 years old. It has ingested a few thousand rounds of standard, and hundreds of rounds of premium defensive ammo in +P ratings. It is still tight, and always goes BANG. It has darned little finish left on it from years of pocket carry, but heck....it was never meant to be a BBQ gun.
I retired it a couple of years ago in favor of a new Taurus 905 snubby in 9mm, which I had a 'smith punch out to .38 Super (more on that project later) which is....a FUN as hell little pocket wheelie.
