Nuttin' in my design alters the stock trigger pull............I don't even think that to be possible.Any mod that shortens the pull would most probably render the safety non-operable.EZ to increase pull weight with a heavier trigger spring.
Seems strange, not sure if there was a change in the design from the prototypes I have installed, as my Winnie has a shorted trigger pull then my 880 I did the mod to. I do have 2 of his new kits but have not gotten to doing an install on them as of yet.
Can't say as I have ever given any consideration to trigger overtravel..Once the gun had fired, I quit pullin'.....kinda like always finding something in the last place you look....
I can run some across the crony today, IIR I found the 13.4 gr JSB .177 are the most accurate pellet I have shot out of my 1977, I will report back on the velocities in a few hours.
