Does Charter still make the Pathfinder? Back in the 1980's I had one in .22lr, and really enjoyed it as a woods walk around gun when I didn't feel the need for a big bore. Adjustable sights, compact, light weight, and fairly accurate (at least enough for plinking and close range small game). Never needed service, but understand Charter has a good reputation.
My experience with Taurus is not good. Quality varies, and if you get a good one, people are happy...BUT, if not, or you need service, good luck. Not sour grapes, just experience with multiple examples..
Rossi?, cant say, but I would do a little Google searching first, and see what people are saying. A good surface polish does not translate into properly dimensioned parts and fitting..
Rugers, both the single six line, and the newer D/A revolvers are about the best bang for the buck, both in quality and service. S&W's run a little more $, but also offer very good quality, and service second to none. You note I mention "service" a lot - it can be important. Re-sale value is also another consideration, with S&W and Ruger at the top of the heap..
