FWIW, Charter replaced my single-cylinder, .22 Mag 4" Target Pathfinder 2 years ago, under warranty, after earlier "repairing" the first one I bought.
As an apology, Charter's Prexy was kind enough to make my replacement the prototype (complete with a special SN) of their "soon-to-be-introduced" Dual Cylinder model, with both a LR & Mag cylinder.
(That Christmas, the Dual Cylinder was catalogued)
Although the warranty process was bothersome, the outcome was outstanding -
The Charter Prexy personally told me (he answers the phone there at times) that his goal is to make his company the best in the US for service and quality of products, at a decent price.
I KNOW he's there, on service - and the prices are right ( I've since bought a .44 BullDog).............
