Oh yes, they do!
I saw a stack inside the gun crib that were obvious, older Charters from the Stratford, CT days from the 1980s and earlier. Maybe a dozen or so that were awaiting inspection/repair.
The two most common problems I see are out of spec cranes and some where the cylinder stop gets stuck due to burrs in the slot cut in the frame.
They're good guns, but they need some polishing when they leave the factory.
Design wise, they're easier to fix than S&Ws Simple frames, coil main springs; ejector functions as a back up cylinder release (on non-shrouded versions) crane is positioned 90-degrees sideways so the thick part reinforces the frame rather than bisecting the frame
making the gun a little stronger than comparable sized models.
If they spent more money in polishing/finishing, they'd have a really top notch product.
I'd say call Charter at : 203-922-1652, ask for a technician. You'll probably get Terry or Nick Ecker himself (the President), tell him what's going on and he'll ask you to ship it
to them. Ask them to polish it up a little, too. It will be slicker when you get it back
