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.

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.

Made a bad trigger almost perfect. This was a horrible pull, now it is a clean ( as strickers go) pull around 3 to 4 lbs. This will improve any ones group ,even mine..You need some patience while getting thru an install, I did not watch the video of ,how to,so winging it took 4 hours +,so I got to do most every thing two or three times, called the learning curve. Any way the results were great. A word to those that aren't kitchen table Smith's, send it in to these folks, worth every penny. I have 2 T.C. compass rifles to get to ,so I expect great triggers when I get round to it. Good people to do business with and don't be like me ,ask them any questions that may come up,pretty sure they got our backs.....God Bless the USA...

My first mod, on my new Shield Plus, I prefer light triggers for 3 shot placement. And I have gotten a few OF these kits Always from MCARBO! Quick shipping, quality products! And now I have the new kit installed, and it functions well as stock. Just need to test it at the GUN CLUB, soon.

I just Got a new Shield Plus - and Had to try M- Carbo kit (again)--- after a did a Complete Disassembly- cleaned it ( cause S&W don't after they Test fire it ) --- but I did Polish All Contact Surfaces ( metal to metal / plastic to ) & deburred the Polymer Frame- then did a Thorough cleaning Before Installing the Spring Kit from M- Carbo. WOW ! Was that An Improvement ! Awesome "Smooth take up - Firm wall -Crisp Break to the Striker! Very Nice Smooth Light / Short Reset.. Now if M-Carbo Could Make a Better RECOIL ( STEEL PLEASE) - For My Arthritic Hands - I have Issues Racking any Pistol these days .... I just hope When I do find A Lighter Recoil setup / it don't Make the Muzzle Rise worse or the Recoil harder.. we will research that later. Right now I want TO GO TO THE RANGE - And test my New Carry Pistol .....

I installed the spring kits in my shield 2.0 .45 and my dads shield .40, absolutely a great value for these kits and made both of these completely different guns. The factory triggers were about 7lbs and rough, after the install triggers are around 4.5 and much smoother. The price point is great and the videos were very useful.

Installed the kit but didn't feel much of a change in trigger pull until I went to the range a shot approximately 100 rounds. Definitely a noticeable improvement now.

At first, after installing and polishing, following the video, I wasn't very impressed with the lightness of the trigger pull. Took the pistol to the range yesterday and put 100 rounds through it and I gotta say there's a definite improvement in the trigger pull now. I guess everything just needed to settle down with some firing, I'm going to get the kit for my M&P 1.0 full size now.
