Just something special about M15's - everything you need in a .38, including great sights.
One of my first 'retirement jobs' after my LE career was working p/t in a large, busy LGS.
One day a fella came in and either traded or sold a finish-challenged blued M15 4".
It had all the signs of having been a well-worn LE or perhaps Security revolver.
Before the guy left, I approached him and asked for 'the story' on it - he really had no idea. Stated his brother got it at a garage sale years before. No story.
Anyway, decided since I didn't have a M15 that this might be a good one. Mechanically very sound and tight as could be. Boss/owner made me shell out $150 for it.
S/N puts it at c.1970
It sees a lot of woods carry at the hunting lease, often with a couple of shotshells first up in the Summertime.
Great on the range, very accurate and don't worry about it getting a little rough use.
