My first issued revolver was a Colt MKIII .357.
I was young, single and a full-fledged gun geek and constant shooter by then. All the issued Colts on my entry to the PD were used. Some very used.
Anyway, through copious amounts of range time and recreational shooting, I seemed to go through a number of those MKIII's.
Rear sights would occasionally go missing and not found, and I'd receive another one. IIRC, had issues with trigger return on one, got another.
Think the last one was one I recall the most.
I'd been out shooting the MKIII at a large Corps of Engineers lake-building project before it was flooded. (Simpler time, no one cared)
Ran a mix of the usual variety of .38's and .357's through it.
Came home, a quick cleaning as I was scheduled to work 2300-0700 that night.
Worked several nights and somewhere near the end of the shift cycle, went shooting again. 'Click'. No primer indent.
Checked - firing pin in frame was absent. Just not there.
Evidently, around the last shot fired several days before, the firing pin went missing.
Meaning - I'd worked about 5 or 6 night shifts without a functional revolver and was completely unaware.
So, armorer was called in from off-duty and issued me another.
Soon after that the department went to S&W M66's. Did my best to wear that out too, but real adulthood was on the horizon and I never did.
So, just that little exposure to the Colt MKIII's has always colored my feeling about them.
