Well I braved the rain and mud today at my local gumbo roaded shooting range outside of town. A pal of mine with the same firearm (Sig p320 compact 9mm) joined me to compare his, which is original, to mine after the upgrade. I don't have a trigger gauge but I felt a slight difference between his trigger and mine. He stated outright that he was signing up for the upgrade as soon as he got home because he liked the new trigger better. I could only tell a slight difference (other than the missing double click) so who knows. As far as accuracy and reliability, no complaints. Just as accurate as before and didn't have a single malfunction in a little over 300 rounds. 100 of which were WWB 115 grn FMJ. The remaining 200 were defense style ammo including Sig V Crown 124 grn, WWB 147 grn JHP, Hydrashocks, Golden Sabres, PDX1s, Hornady Customs, and Barnes Tac XPDs. So the upgrade certainly didn't screw anything up far as I can tell.
