I've been shooting a SW40VE for about 14 months now. I love the reliability and egronomics of the gun. It's the trigger that's really starting to bother me. I don't shoot it much better than my two inch J-Frame .38--which isn't bad, but is bad for a full-sized combat pistol. The Sigma has the potential to be a good shooter with a decent trigger. Any suggestions on improving the trigger?
