Quick heads up for people following this thread and haven't seen this thread
Pistol For AGF comp there are some discussions on tuning the trigger. It does make a marked improvement but a quick word of warning (copied from my reply on that thread) :-
I switched out the adjustment screw on the trigger blade with a 12mm grub and started to play. Wound it in until the sear would not engage then backed it off until the sear could engage and then backed off a further 1/2 turn. Shot a quick card and massive improvement - whilst still a bit heavier than I'd like (until I can get the plate off and swap springs about) I had a lovely crisp single stage and this showed on the groups - finger nail sized for 10 shots with just a pair of pulled shots that I knew were me. HOWEVER, what I hadn't noticed until I was giving it a final check over was that the safety was now disabled and the pistol could be fired with the safety in either position. Played with the adjustment until the safety would function and it was a fair bit of backing off and the trigger whilst better than original wasn't as good as when the safety was disabled. Now this is not an issue for myself as apart from the HW45 none of my pistols have safeties and I rely on proving any gun is cleared and decocked before putting it down (old habits from range officer days), but it may catch someone out if they assume the safety is still functioning after doing this work.
