I did a search here, but didn't find anything that directly addressed the information I'm seeking. So, here's my question.
What is the "lightest" DA trigger pull weight that can reasonably be achieved and still reliably ignite Federal primers? And, how is this achieved?
I've read the Kuhnhausen manuals and worked on a couple of my Smith revolvers (Model 19 & 686) to try to achieve a "great" DA trigger. I think I've achieved some success, i.e. pull weights reduced from 10+ (off my trigger gauge scale) to 6 1/4 - 6 1/2# and very smooth. However, I have read on other forums of Smith DA triggers in the 2-4# range. I would like to achieve this. Can anyone tell me what else needs to be done, beyond what is described in the Kuhnhausen manual, and replacement of the hammer & trigger rebound springs? I should add that these revolvers are not self-defense weapons, they are my NRA Action Pistol competition revolvers (primary & back up).
