Got my first two old model Bearcats in the mid and late 60's, then bought a Super Bearcat in '69 (also an old model). Still have the SB, my favorite 22 revolver to just stick in a back pocket for decades. I do have two holsters for it, a Hunter leather hip and a custom leather cross draw, but have never used them. After so many decades doing so it just "belongs" in a back pocket to be on hand for any use. The SB has 10's of thousands of rounds through it, still shoots like new, has always scored cook pot fodder just fine, took its share of rattlesnakes and saw endless shooting just for fun. I never found the non adjustable sights to be a problem on any revolver. With lots of use they point and hit where you look just fine, and faster than having to line up sights. At 6-1 I also never had a problem with their smaller size, just learned to adapt to them and shooting them very well became second nature.
Never had a new model Bearcat. Being old school, especially when it comes to single actions, they just don't fit me. A new model would be a fine SA for most folks though. All of my Ruger SA's have been old models except for 2 of the 3 44MAG's I've had, and a NM 357MAG Blackhawk bought for a short time after I let a friend talk me out of an old model Blackhawk... until I found and replaced it in turn with another old model BH (that I still have). My only remaining Single Six is also an old model 22MAG, but I had other OM SS's. I've shot those of friends, but have never owned a NM SS.
