I took my new M85 to the range today intending to run 100 rounds through it, stuff happened. Had about 40 though it when something fell onto my strong hand, wasn't wearing my reading glasses so I really couldn't tell what it was. I placed it on the bench and opened the cylinder, dumped the empties and loaded 5 more. Couldn't close the cylinder, strange. It then dawned on me what I had placed on the bench, so glad I hadn't pitched it. Not having reading glasses or a screwdriver my day was done. Took everything home, bought a small bottle of blue LocTite on the way, a little dab and a good screwdriver and all is well again. The little gun is a very good shooter.
