I purchased a new Charter Arms Undercover in 1970. (give or take a year or two).
For me the little revolver was fine. It was as accurate as any J-frame Smith or Colt D frame (Detective Special/Cobra) and seemed a bit smaller and lighter.
I kept it until just last year when I gave it to an Uncle of mine who installs AC's in homes in Savannah, Georgia and needed it for personal protection more than I did.
I think you can still find new CHARTER ARMS UNDERCOVERS on wwwgunsAmerica.com. In fact I saw one on there recently in what looked like stainless, but probably was "satin" something. It looked very nice and wasn't too expensive. I can recommend an original Charter Arms Undercover without reservation, but wouldn't touch any of the later reincarnations. (Charco, etc.)
I think I've become a bit of a "gun snob" in my doteage, as I lean towards Smith & Wesson J-frames, and Colt Detectives, or Cobras now.
If you take your time you can find a very nice used Smith or Colt for probably not much more than you would spend on a Charter. If you ever expect to resell the firearm you will certainly do better with either than the Charter.
Still, if someone came along and offered me another original undercover for a cheap price I would buy it in a heartbeat. I do NOT consider the original Charter Arms Undercovers as junk by any means.
Best Wishes,
