Something else I learned from shooting Glocks for over 18 years is that a lighter trigger pull by itself doesn't help me shoot better. I've tried every mod possible and ended up going back to stock parts with a few exceptions. Glock OE Minus connector and the NYPD Orange trigger spring. The pull is like 9-10 lb (off the scale for my wheeler gauge). Sounds terrible but I shoot it mainly at 25 yd, standing, unsupported and have no issues with accuracy. It really helps me train to improve trigger pull and grip.

The M&P 2.0 Full is a 4 lb pull, same as the Shield Plus, but for some reason the M&P 2.0 Full is a cleaner and crisper break. The Shield Plus doesn't feel as good. Some theories I have is the smaller and lighter stature of the Shield Plus contributes to this.
