is there any way to shorten the trigger pull on the 40ve or get a 1 piece trigger

Ah yes, the Sigma and its "algebra problem" trigger (long and hard).
IMHO, love it or trade it. It is a good reliable entry level defense pistol in stock form. I use it for trainers, and strongly advise against trying "improvements" to the trigger; most anything besides polishing seriously impacts reliability. The two-piece trigger is one of the 3 safties.

mainly the 2 peice trigger isnt a problem that i can tell i havent had a chance to shoot it there's a difference between dry firing it and pulling the trigger and hearing boom
