I bought a 4" Charter Pathfinder a couple of years ago. Mine is the combo, with both 22lr and 22mag cylinders. It shoots just fine. I will say that the trigger has some stacking in it, more than any of my other revolvers. I can't compare it to the Taurus which I've never handled, except to say that charter's customer service is miles ahead of Taurus at the moment.
I would feel pretty comfortable recommending a Charter 22 mag, especially if you can handle it to test the trigger first. They are relatively inexpensive, made right here where we live, and the lifetime warranty means something to the manufacturer.
