Can anyone tell me which screw(s) increase or decrease hammer/sear engagement? Can the engagement be adjusted and still maintain a decent two stage pull? I am trying to eliminate sporadic multiple discharges.

Thanks Spenser.

The Pilkguns SP20 is excellent but suffers from copying the origianl Hammerli diagram which is poorly drawn. It is impossible for me to identify the function of all parts shown and in particular, impossibe to tell if screws affecting slack force and slack weight merely apply spring pressure or change the physical relationship between hammer and sear and also what appears to be some sort of sub-sear.

Huh? Sub-sear? Physical relationship? Sear engagement is #35, 2nd stage weight is #34, 1stage weight is #8, 1st stage travel is #15, 1stage pickup is #7. Where is the potential problem? IMHO, there is no other trigger on the market which can be adjusted so easily and which shows so clearly what-happens-when... If the only thing you have are sporadic doubles, I'd adjust #35 by a small amount, and that's it... or did you try something else?

Thanks Tycho. Your information is exactly what I was looking for.
