New 1860 just disassembled to clean prior to shooting. Withdrew wedge per instructions. Reassembly stymied as wedge will not return--hangs up because inner wedge spring jams on right side slot, it looks like this inner retention spring should have a bevel to allow passage. I appreciate advice from the experts as to what next? Return? File wedge spring? (I am not much on metalwork) Thanks for help, Ron in FL
