Found a Colt Trooper MK III 22 caliber in a local gun shop. Serial # is Y133XX. Looks to be in excellent shape but does not have original or correct grips (has Pachmyer Rubber grips). Asking price is $399.00. Two questions. Is the price in the range of what this revolver would sell for and what year is it (I looked at Proofhouse.com and don't see that serial number listed). Last question, would the same grips that fit a Python fit this frame as well ( I have an extra set of factory Python grips). Thanks for the help.
