5 star great product for a great price

Rating:
Pros:
Cons:
Shipping and customer service were top notch. Followed along with video which was easy to follow and detailed. The trigger feels much smoother. Crisp break. I don't have a trigger scale but it feels way better than before. Do yourself a favor and order the polish kit while the gun is apart. My POS computer wouldn't let me click on the 5th star but I would rate it 5

Still 5.5 lb trigger

Cons:
Installed on 1st gen 9mm Shield. I ordered the polish kit, CLP, and gunsmith block from M.Carbo. Got a 2 sdp Dremel & hammer off Amazon. I followed the You Tube instruction video carefully. Trigger pull feels smooth but still heavy, measures 5.5 lbs. I really hoped for close to 3.5.

Helped with a MA compliant trigger on a .40 cal 1st gen shield

Rating:
Pros:
Cons:
I recently ran across a deal I could not refuse on a .40 cal S&W Shield 1st gen. The guy getting rid of it hated the trigger pull. Even though we live in North Carolina he had a MA compliant pistol with the supposed (10.5lb trigger). When I bought it, I used my digital trigger pull scale that maxes out at 12lb, well it would read "over" prior to striker fall every time!!! I thought about getting a Apex trigger kit but then I ran across the M*CARBO spring kit and decided to try this kit. After doing the work described in the video the trigger was much smother and went down to 7.8lb trigger pull. Still wanting to improve it I found a old striker block from a 9mm shield I had done a trigger upgrade on in the past. After polishing it and putting it back together.............. I am now getting a 4lb trigger pull!!!! and as stated in the video........ as smooth as butter!!! Thanks M*CARBO

S&W M&P Shield Trigger Spring Kit

Rating:
Pros:
Cons:
I purchaces a kit a few months ago for my M&P Shield 9mm. Trigger pull was awfull for a 2.0. Pollished parts and installed as decribed in online video. Wow..this is how they should function from S&W. My wife liked it so much she bought a 9mm and I also obtained a 40S&W Shield.We ordered kits for the both and I went through the ritual. Before and after function does make it a ritual compared to what the factory calls a firearm. Also like to add M*CARBO is very fast getting your order to you and packaged so no damage should occure.

Shield 9 M1 and M2

Pros:
Cons:
Just finished polishing and installing the Trigger Spring Kit on my latest Shield 9, M2 with built in laser and give the product and process an A+ across the board. The trigger pull weight and smoothness is heavenly and I'm ordering two more spring kits for my other two Shield 9s M1's and expect the same result. Thanks again for the service, product, and quick delivery.
