Hi Everyone,

I am having a lot of issues with the trigger weight on the Walther LP 400. Specifically, after shooting 3,000 to 6,000 shots, the trigger weight drops to less than 500g. I have used Morini before and never ever encountered such inconsistency. I have to increase 2nd stage (total weight) to over 520 and it will stay that way for 3-4 months or about 5,000 shots and then drop to less than 500g.

Is anyone else having the same issue and has Walther been able to fix it. My pistol has been with Umarex several times but trigger issue is still not resolved. My first stage is less than 200g. (It was 300g, but Walther indicated that the trigger will fail if first stage is kept at 300g; so, I tuned my shot process to adjust to the lower first stage).

I appreciate feedback from this forum.

Thanks, Nina

what did they mean "it will fail"?

Sorry I do not get it. Walther was suggesting that you should have a first stage lower than 300g not to face the problem you are having?

Answer: I mean that the trigger weight drops to less than 500g. So, it does not pass the trigger weight check. This can happen anytime during a competition and the range officer can request trigger weight to be checked after the match. If it fails, the shooter is disqualified.

Answer: Yes; Walther is suggesting that the first stage be set to less than 200g otherwise the total weight can easily drop to less than 500g. On my Morini with electronic trigger, I had it set to 350 with no issues. Coaches do not recomend this method due to fear of early shot/release but I am used to it and I have never had any early shots (in white/on approach) due to light trigger with the Morini. But, with Walther, the trigger weight drops and there is no way of knowing it has dropped without an early release.

In the past Ulrich Eichstaedt, author of the article on Visier which describes the tests performed on LP400 and now working for Walther if I am not mistaken, wrote that I was to much of a beginner to state that the trigger of LP400 is not good.
So I am a bit scared of commenting on this.... However I cannot stop myself from asking the more experienced shooters in this forum the following question:
Is it not unusual to have first stage less than 200g?

The correct answer is: It depends. Trigger weight is a personal thing. It should be what works better for you.

But with that being said, a light first stage implies that the second stage (when the trigger breaks) is heavier, and so, you'll have the tendency to apply more force than needed, which will increase the results of poor trigger pull, hence worst shots.

In other words, if you compare a second stage weight of 350g to a one with 150g, you will probably jerk the first trigger more than the second. On the other hand, a lighter second stage does imply that it is more likely that you may have a premature departure of the shot from time to time. But that can be fixed with some training and dry fire.

Hope this helps

I have much less than 100g on my LP10e and I never shoot too early. However I have tested a MGH1 (may be 30 shots only) which was set with an extremely light second stage ( I guess must have been less than 50g, but I did not measure it) and, although I loved that set up, I have had a few early shots. Probably, however, I loved the MGH1 set up because it was increadibly crisp.
