bearcats
I've got one too. Early model, can't remember the exact date I researched, but it was very early 60's as I recall. seen some use, but entirely functional and not abused. Surprisingly, Bearcats seem to get a lot of grief due to their tiny size, but for me, its that very thing, how small they are, that I find useful. They fit about anywhere. Mine has a steady home in the pocket of my big wool pants while bowhunting (legal here). I don't see it so much as a defensive weapon, but more as a signaling device,that could be pressed into use as a weapon. I find the sights a bit hard to see, and can't hit much with it past coke can distance. But for that sort of thing, their a hoot to shoot.
Last I looked into the Ruger factory "upgrade" to a 6-shot carry, Ruger indicated they would keep the old parts. Not for me. So mine stays as it was when first released, loaded with 5 and an empty chamber under the hammer.
