This spring kit will will reduce the trigger pull in your M&P. But we recommend using this kit only for competition. If combined with one of full trigger kits we advise using the Heavy Sear Spring (purple) instead of the Competition Sear Spring. When installed properly, this drop-in kit will:
– Reduce trigger pull weight
– Direct drop-in replacement parts, not fitting required
DOES NOT FIT for M&P M2.0 models. Does not function in the M&P Shield models.
