Followed the video and had no issues gave it a very smooth lighter trigger
Spring kit made a HUGE difference in my S&W Shield 40 build. Trigger is now crisp, clean with a definite reset point. Install was fairly easy using Youtube videos. Highly recommend MCarbo spring kits.
I found the M*Carbo kit to be extremely easy to install with the video. My pistol has new life and I can feel the difference in the trigger pull/response at reset compared to the original components. I bought my Shield 40 slide assembly via Ebay and changed my 9mm over to the 40 cal. I am ecstatic about the performance difference. My 40 is very controllable and a pleasure to shoot. Thanks M*Carbo.
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.
I have successfully installed the trigger spring kits on various pistol models and have always been happy with the results. When I was ready to do my Shield 45 install, to my dismay, I discovered that there was no installation video available. I was able to complete the install but would have been happier if a video was available like there is for many, many other models. I hope that what I believe is an oversight will be corrected quickly. Thank you and keep providing the excellent products that you offer.
Great spring set works good, buttery for a S&W Trigger. Worth the money
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.
GOOD PRODUCT ***WATCH THE INSTALLATION VIDEO** and keep it on hand during the work. I did it the HARD WAY!! The video for the Shield is on YouTube NOT on the Mcarbo web site. Watched the video once days before starting and just tore apart the pistol and I couldn’t find the video during the job!!! Now I know how to Take down and rebuild the Shield forward and backwards. Don’t forget the separate polishing kit! Well worth the $12.00 or so for it. I don’t have a trigger pull gauge, though the trigger feels much liter, no grittiness and short reset.
What an improvement once the kit went in......Love it
Got my stock shield plus with stock trigger and stock sear down to 3.6 pounds! Yes 3.6 pounds! Couldn't be happier. Ty mcarbo.com.
Finished the installation, and the trigger on my Shield Plus measures 3.5 pounds. Couldn't be happier. I wouldn't want it any lower than that.
I had some doubt about how much improvement there would be because: 1) it's supposed to be less effective on the Shield Plus, and 2) the Performance Center model is supposed to be even more tuned. There were plenty of rough edges to smooth out, even on the PC model. Once I finished and put it back together the pull is about 1.5 pounds lighter and smooth as silk with instant reset. It is on par with the Apex trigger I put on my M&P 2.0. In short, enormous improvement worth much more than the modest price of the kit. Highly recommended for every Shield.
The spring kit is definitely worth the $24. So far, I have installed the frame springs, and polished the sear and disconnector. Prior to any changes, the trigger pull was measuring 5.5lbs. It is currently measuring 4.5lbs. I'm hoping for another half pound drop, after adding the slide springs, and polishing those engagement surfaces. That'll put the trigger exactly where I want it, for a carry pistol. Time to order the Glock spring kit.
Makes the blah trigger of 1.0 pull nice and crisp.
good upgrade for a great gun. noticeably lighter and smoother trigger pull into a nice crisp break. video was easy to follow along with and gave good description on everything that needed done in the video.
Gotta say, this was the best 20 bucks spent on my shield first gen. Better overall trigger feel with the bonus of a lighter trigger pull. The cherry on top is supporting a fellow veteran.
