Okay, mine cooked up some kind of extraction issue; spent casing left partway out of the chamber, slide flung far enough to the rear to pick up the next round, which became jammed under the first one in a double feed jam.
Sent the pistol back to Kimber; gone two weeks, and returned (apparently) fixed. Gun was back to its old habits of eating about anything I fed it, including WWB 115s and 115 reloads, along with a couple mags of 124 Gold Dots.
Repairs consisted of adjusting the extractor and polishing the chamber; shot the snot out of it the other night without a single problem
For the OP, the Solo was never meant to be a target gun; try shooting it at 'combat' distance; aka, 21', and draw slowly and deliberately on the trigger until it goes bang. Ever shoot a revolver double action? Shoot the solo the same way.
