M&P Spring Trigger Kit
These Trigger Kits are awesome! My gunsmith installed it for me ( which I recommend) ! You can pay upwards of $ 180.00 for an Apex trigger kit that is the same!

Worked great for me
I bought this for my gen1 45C and installed it today . Trigger pull before was a very long 10.75. after the polishing and install of the kit I noticed and compared it to another gen1 but it shortened the trigger pull and and lightened it to a average of 6.25 . Which is better than my 2.0 .
I was highly impressed with the performance and improvement overall and will be buying more to upgrade my other smiths
Did Not Work For Me, Again
I bought this kit before and with everyone success, I thought I must have done someone wrong, so bought kit a second time. I have a S&W M&P 9MM 1.0 Compact and the trigger pull weight was 6.7 LBS (before). Ordered a second "Smith and Wesson M&P Trigger Upgrade Kit 1.0 & 2.0 - 9mm | .357 | .40 cal | .45 ACP", followed the video to the tee again, had my laptop with me, watched the MCARBO Video as I went through the steps, one by one. Spent 3hrs on the trigger job, again wanted to eliminate rushing errors, but no joy. Measured the trigger pull weight, it was 6.7 LBS (after), no change, sad :( . Fool me once, shame on you, fool me twice shame on me. If anyone has any suggestions, please advise. Not mad, just confused and disappointed. My next step is to replace the triggers with an Apex trigger.

Works in a shield plus
I bought this on a whim for my shield plus to see if it fit, I figured if it didn't fit I'd just put it in my old shield 1.0 instead. Well it turned out to fit fine, the trigger pull is vastly improved over the stock shield plus trigger. Totally worth the $25 and elbow grease putting it in.
m&p 2.0 10mm
Quality product, easy install. Improved reset and dropped trigger pull weight by half.
Signifigant improvement, but not as much as promised
I've installed several of your kits. The latest went into a 1st gen M&P 45. It started off with a pretty horrible gritty 6 lb. 4.5 oz trigger pull weight. The gent I got it from claimed it had an "Apex kit" in it. Springs perhaps, but the striker block was dead stock, not the rounded one Apex sells. As usual the video was Very Helpful, and it really helped me out. One curve I was thrown was instead of a guide with a nipple on it for the striker block spring I had a flat piece of stainless steel. That took a while to install, amazing what one can do with a thin wooden chopstick, I drove the spacer down, slid the rear sight over far enough to jam the 'stick, and then slowly removed the 'stick. The rest of the job went well. I have your polishing setup with the nice dremel tips and Flitz so things got nice and smooth and shiny. Once it was all back together I measured with my Lyman digital gauge an average pull weight of 4 lbs. 7.1 oz. Not exactly a 50% pull weight reduction, but the trigger IS a lot smoother due to all the polishing work done.
Smith and Wesson M&P Trigger Upgrade Kit 1.0 & 2.0
Installed this upgrade in a brand new S&W M&P 9mm v1.0 I purchased for $279 that was collecting dust on a resellers shelf. The upgrade was augmented with an Apex Action trigger, trigger only. I only used the MCARBO parts with the bare trigger. The combination gave me a fantastic trigger group for $70 less than the cost of the whole Apex trigger kit. The result is outstanding. The 3.5 lb pull feels like "butter". Combination reduced trigger travel by more than 50%. No trigger creep or spongy trigger. The trigger break is crisp and breaks clean. The trigger reset is much shorter and has a great feel to it.
Will this work on a Shield Plus Performance Center (9mm)?
You will need the Smith and Wesson M&P Shield Trigger Spring Kit 1.0 & 2.0 - 9mm | .357 | .40 cal | .45 ACP
Will this work with a M&P 9c?
Yes, it will work on a 9C.
I understand that the 10mm is built on the 45 frame. Is that accurate and will the upgrade work on the 10mm M&p?
We tested it on this caliber 9mm / .357 / .40cal & .45ACP. The 10mm wasn't tested. We can't recommend if it will work
Anyone install this on a M&P Shield Plus? If so, how are your results and how rounds down field with the new trigger
