I own a couple M&Ps already. Am older shield model and a 4" compact model. Looking to add a full size 4.25" 9mm model and am trying to decide between the standard 2.0 version pn#11521 or the Performance Center 2.0 version pn#11818. Use would be rec shooting and some carry. I am used to the Truglo Pro day/night sights on my other M&Ps so would probably add those to the new 4.25". Is the trigger worth it on the performance center version over the standard model? Any other upgrades the performance center version offers over the standard besides trigger and sights?
