trigger travel

I'm no gunsmith, but it seems to me by doing that you are setting the rear of the sear bar out from the frame. That effectively reduces the depth of the sear that engages the firing pin. That would appear to me to create a less positive engagement which could result in the firing pin not being caught causing a slam fire (not sure that would happen since I don't think the firing pin has enough inertia to detonate the primer) or it might cause the firing pin to slip the sear without pulling the trigger and possibly lead to the gun going full auto.

There is an article by Mike Gorman in the "Shooting Times" edition of May 1974 that shows how to "tune" a Luger trigger by polishing the sear and using set screws to take up the creep and backlash in the trigger. This does modify the trigger so probably should be done with a spare trigger to preserve the original matching part.

I have three .jpg files of the article that are around 240 Kb in size. I do not know enough about copyright laws to know if it is legal to post them here on the forum but I could email them to you if you are interested. Just email me at rwood1@elp.rr.com and I can send them to you. This is for information purposes only and I assume no liability for any use of the information to alter a Luger.
