Ray, if you do the '15 minute trigger job' you find in the online sites that involves cutting one leg of the hammer spring off don't be surprised if you start getting misfires! I know the articles usually say 'totally reliable' and 'no misfires at all' but that's bullschitt! I've got one of those modified springs lying around here somewhere and there's a reason it's not in a gun anymore, I like my guns to go bang EVERY time I pull the trigger! It made for a great trigger pull but the reliability wasn't there. Now I do like Mike suggested above and just use the JP red & yellow springs, the JP 'Enhanced Reliability Spring Kit'.
