Would buy again - Apex Tactical Specialties Action Enhancement Trigger and Duty/Carry Kit for S&W M&P Shield

This kit took most of the slop and the gritty feeling out of the trigger. It now has a much crisper break to it and feels much better to shoot. I didn’t do the full 5 because I decided to use the factory spring, like most recommend, in order to keep the trigger pull lighter and it seems like most people do this anyways. Pretty easy install as well
