Troubleshooting my new luger.

[Frater]

Hello all. This is my first post on this great forum, treat me gently.
I have purchased a DWM 1917 Arty luger from forum member Kress, pictures and some background can be found in an earlier thread of his regarding sight problems. It is mismatched with a Tikka barrel so it will be a shooter.

When cleaning up the guts of the gun I found two parts that may need attention.

The firing pin spring rod appears to have broken off from the rear spring cap, the break seems to have happened some time ago and I wonder if this can cause problems. It still performs its task but can travel back and forth during action.

With the thumb safety on safe I noted that pressing the trigger causes the sear to flex outwards enough that the firing pin hook gets hung up on the edge of the sear. Arming the gun puts it on hair trigger since the sear has not reset all the way back. What is the best way to fix this? Improve sear spring tension, polish engagement surfaces? Ideally the sear should not travel at all when the safety is engaged IMO.

More questions to come after I've fired it for the first time I'm sure.
