I just got done installing a NY1 trigger spring I gotta say I am impressed. The trigger feels much better for the few rounds I got to fire. I used my existing 5 1/2 lb connector and didn't notice any difference in pull weight. To me the pull is lot smoother like my other double actions. I differently like it and for 1.99 it was a stealer deal to make a unbearable trigger a little nicer. I did notice when field stripping the gun you have to pull the trigger back or the slide will get stuck only down side I found to it so far. So anyone else used the NY1 spring and how where your results? "Sorry about the spelling my spell check is acting up"
