First things first. I hated the trigger on my M&P 40. The curve was so extreme I would actually get a blister on my finger when firing large volumes of rounds. I have been wanting to replace it for some time. The Tunney trigger looked promising and the price point was great. The installation instructions and video were easy to follow and after a couple of simple operator error set backs, the trigger dropped right in. Using snap caps everything seemed to function properly and the trigger pull was light, about 3 lbs, and crisp. Took it to the range and after becoming more comfortable with the light trigger pull, I was extremely pleased with the results. I will need more time to become comfortable with it, but I look forward to any excuse to spend more time at the range. Highly recommend this trigger for your M&P 40.
Pros:
Positive reset
Crisp & clean break when firing
Cons:
none so far
Would Recommend:
Yes
