Troubleshooting my new luger.

[Lugerdoc]

Frater, It appears that your shooter luger has some improperly fitted parts. The trigger bar (sear) SHOULD move a bit when the trigger is pulled, ever with the safety on. It should move back to it's original position when the trigger is released, so the over lap of your striker to the sear is NOT within specs. If you decide to replace the striker, I would also recommend getting one with the relief cuts in the front for added protection from a punctured primer. The spring guide part of your FP retainer is not from an original WW2 or before retainer (should be tapered). I do have original retainers available @$25 or new postwar Mauser Parabellums @$15. I also have orig reliever FPs (strikers) or sears complete @$50 each. Changing either of these may affect your trigger plull and/or FP release, since not all luger parts are interchangable without some fitting. Finally, just because your receiver is notched for an LPO8 rear sight, does not necessarily indicate that an LPO8 barrel was ever installed. Your Finnish barrel, most likely replace a worn 4" barrel. The Finns also used many Swiss replacement parts after WW2 as that was the only source still making them until 1950. It sounds like you need a competent local gunsmith to check your luger, before you blow a breech block or something more serious. TH
