S&w shield 9mm 1.0 - Apex Tactical Specialties Action Enhancement Trigger and Duty/Carry Kit for S&W M&P Shield

Purchased this kit for my Shield 9mm 1.0. It was not an easy install but not very difficult either, just plenty of patience required! I suggest to put several layers of electrical tape over the Apex trigger when driving the retaining pin to prevent scratches. The retaining pin on the new trigger was the hardest part of the install. I followed the Apex instructional video on youtube, just be patient, take your time and the install will be completed in about an hour!
