polish...
 
Hi ollie, I agree, polish and springs could make the most dramatic improvement, with out sacrificing safety... Any time you start grinding.. well, let's just say, A lot of other things have to be right first... :jumper::jumper:... Best to all, til...lat'r...GT

Just by polishing areas indicated in red to a mirror shine (without changing geometry) Luger trigger action can be improved significantly. (DO NOT USE DREMEL FOR THIS)

Second part would be to install travel adjustment screws. This can be done on trigger itself or sear bar. There are multiple locations for this.

Third step in improving Luger trigger feel is to eliminate wobble completely from the plunger. Maybe required to built entire new and longer plunger. Longer means it will have to be seated deeper in new drilled hole.

Anyone can accomplish first step and immediately benefit greatly improved trigger.

I have found that changing the springs have proved to work out very well for me. The cost is not very high and you can easily change them back or mis-match them to what you like. I had a BYF-42 with pull that was too light that came out very nice with Wolff springs. I only have one shooter that is causing me an issue at this point.

As measured with the Lyman electronic trigger gauge, averaged over 10 pulls:
Swiss 06/1929 SN 71644: 3.80kg
Swiss 06/1929 SN 77493: 2.57kg
Swiss 06/1929 National Match SN 59951: 2.64kg
Swiss 06/1929 National Match SN 65721: 2.15kg

Data
 
Thanks, Michael for posting the data. Couple weeks ago, Olle came to my place and 'shot' my Borchardt replica....with only a primered shell. He described it as a 'light pull'. We didn't get around to using his gauge to actually measure the pull. perhaps another day we'll meaure my Lugers, etc. and I'll post the results. I like the feel of a light pull, why, too, I like set triggers! I think I'm less likely to pull the weapon off target then when firing with a heavy trigger. Bill

Yep, I actually had the honor to fire it a couple of weeks ago and the trigger is sweet! It's always difficult to "finger gauge" a slick trigger, but it felt like 3 lbs, maybe lighter. We'll check it next time.

My new to me alphabet Luger came to me almost unfired, just a tiny evidence where the toggle stop hit a few times. The trigger, using a snap cap and an actual weight setup (I learned to not trust the electronic scales, a shame because they are so easy to use. ) came out at 4.5 lbs. Someone mentioned a sticky about trigger work but I can't find it. My Mauser built in the 70's has a 7.7 lb trigger! It's my only shooter so I need to fix that.
Also, I read the ebook's info on it.
One thing I noticed about the alphabet commercial, the plunger is a very close, wiggle free fit. I suppose I can just use it's surfaces as a sample for the 70's P-08.
Can anyone tell me if they have used the Power Custom fixture effectively for any of this? Thanks,

I found a sticky "Cocking problem?", that must be it.

The official Swiss military trigger tuning procedure eliminated slack by adjusting the angle of an annealed trigger linkage lever with a special tool, heat-treating it afterwards. I have the tool, but not the instructions for its use. Note that, unlike its predecessors, the P06/29 exposes its trigger linkage via a cut in the sideplate. The Swiss Luger armorer's manual also contains instructions on stoning the sear for optimal engagement. My National Match W+F 06/29 Lugers appear to have been tuned accordingly.

(what is a good trigger pull) One that goes bang when you pull it. Old Blue
