Those who like them are giving reasons. Those who don't are not.
I have an Undercover 38 purchased in December of 1987, on the day I was hired as an LEO. I carried it as an OD/BU gun the first three years, only stopping when I switched to an agency that did not include it on its "approved firearm" list. I still own it, and it has probably seen 700-800 rounds in twenty-plus years, with one failure to fire. That round was, incidentally, part of a batch of 20-year old commercially-sourced reloaded ammunition that had been issued to me by the first department. That round fired the second time the hammer was dropped on it.
My gun is of a rather uncommon version for that period; I have never seen another like it. Though a Charter (not "Charco"), it has a full barrel and ejector shroud over it, of a gloss black finish. The remainder is blued. The gun is tight and shoots pretty much to POA with 140+grain ammo. I have not been disappointed in it at all, and still carry it from time to time when nostalgia kicks in.
When I re-established a relationship with my dad after almost thirty years in the early 2000s, I learned he had one as well, though his is quite older, with five digits to its SN as opposed to my seven. No shroud on his, and his barrel was 1 and 7/8"; mine is two even. He used his for the same purpose as I did mine. He died last year, and his gun is now mine. Like mine, it performs well, though I have not had but maybe 25 or so rounds through it yet.
If I was in the market for another revolver, Charter Arms would be on my list to check out. Wouldn't mind having a Pathfinder myself.
