Walther LP 400 trigger weight issue.
The trigger some times passes 520gms weight test while in the very next test, doesn't even passes 500gm weight. This happens back and forth.How to solve this issue.

Contact Walther and tell them.

Change pistol! :-)
Re: Walther LP 400 trigger weight issue.
This can occur if the sear is set too fine with too little weight
on the second stage spring.
Increase the sear and second stage weight with reduced first stage
and re test.

I had similar problems, on my lp400 because the sear adjustment was very tiny (like 1/12 of a turn) . Then I adjusted the sear for a 1/8 of a turn and got better!
also, Bauer Christian from walther told me:
" Please make your searadjustment 1/6 turn back after releasing and please have a look at you triggerstop.... the springs you have inside the trigger are the latest version and with some gambling on the triggeradjustments you may get about 410/420 and 90/100 to pull in the second stage. 450 +60 is impossible.... you need a specific weight on the second stage from about 120gramms to get the trigger, the sears catching..."
If you increase the first stage, the second stage you feel lighter and your trigger finger movement will be more "controled" !
