Shield 45 spring kit
review-star review-star review-star review-star review-star
When I purchased my S&W shield 45 acp it came with a 10-1/2 lb trigger. I needed to do something to reduce the trigger to around 5-6 lbs. After doing some research I found Apex spring kit @ $100. +. and Mcarbo spring kit @ under $30.00. I went with the latter. The video instructions were great except it didn’t include a shield with a safety. It took a little effort to figure that out but all went well.
I replaced all springs except the sear spring. I felt that the original spring would be just enough to keep the trigger on the high end of 5 lbs. Once the polishing and springs installed the trigger was right at 7 lbs. I went to the range and put a box a box of ammo through it. The trigger now is a consistent 6 lbs. and crisp . I couldn’t be happier. Why would one pay $100. + added to the gun cost. This is a great kit with great instructions. Only hiccup would be if your shield has a safety.

Only reason I gave it 4 stars was because I was getting light primer strikes with ball ammo. So I went back to the stock striker spring! End of story. 3.6 pound pull what's to complain about!

S&W M&P 9mm Trigger Job
review-star review-star review-star review-star review-star
I've never done anything like this before. After watching the video, it gave me the confidence needed. I purchased the spring kit, the punches, the gun block, and the polishing kit. Using the video again I went step by step and completed the trigger job. I notice a significate reduction in the trigger pull. Before doing the trigger job I had difficulty pulling the trigger and keeping the sights aligned. I went out and shoot the pistol this Sunday. OMG, I love it. The reduction in trigger pull was just what this pistol needed. It's now one of my favorite guns to shoot. Thank you.
Nice Kit with Good Results
review-star review-star review-star review-star review-star
Kit was nicely put together and the installation video provided was excellent. This does require some work, take your time on the polishing, it’s worth it. My rear site was not as easy to remove as in the video, so again, take your time. I am not sure about the heavy duty return spring yet, may go back to stock. But need more time shooting first to decide. When testing the pull weight after completion, there was some inconsistency. Will retest after there is more time on the trigger. Overall I am very pleased, big improvement over stock, super smooth take up, nice wall with crisp clean break and reduced pull weight.
