i finally did the installed on my m&p 45 fullsize . wow is all i can say what an upgrade. this is the forth mcarbo kit i have done as usual you guys rock. great product if you haven't done this you need to.
Like the video, my M&P4.25" 9mm had a heavy trigger. Using the video as a guide and just being slow and careful ,the results are a totally different smooth trigger. I think it dropped 21/2 to 3 lbs. off the pull. Polishing is a must and compliments the upgrade.
I have done 3 of these so far: M&P 45 compact 1.0, M&P9 fullsize 2.0(early version), and now the M&P9 2.0 compact. I take pictures of the sub assemblies before I proceed for reference later. The Mcarbo video is for reference only, your M&P may have slightly different parts depending on the version it is. This upgrade brought my trigger pull down to 2lbs 7oz average. Great reset and overall better feel, no stacking, consistent wall, and crisp break. Couldn't ask for more. Preparation and patience is the key to a successful installation.
I ordered the kit for my shield 9mm. And I received the product within 3 days. The company reached out to me multiple times to let me know when it would arrive and to see if I had any issues. The instructional video is a must. I had some issues with the rear sight at first, but once that was removed it was a very relaxing process. I just followed along with the video and man did it make a big difference in my trigger pull and made it so much smoother also
Wanted to shorten and lighten the pull on my full size M&P 9, but I was hesitant to spend the coin on the full Apex kit. Started with the Apex shoe and a good polish. Definite improvement, but still a little heavy. Stumbled upon the MCARBO M&P video on YouTube and figured I'd give it a shot. WELL WORTH IT! Set aside a good 2 hours for polishing so you aren't rushed and enjoy the satisfaction of saving yourself hundreds you'd normally be paying a smith. My final average ended up at 3lbs, and very crisp, clean and repeatable which was my goal.
Installed in my M&P 9c, It went together very nicely and well worth the price and effort.
I am by no means a gunsmith but I do have a little experience working on firearms. The video on this upgrade was very helpful. I followed the video instructions and took my time and the installation went smoothly. I was able to feel a major difference in my trigger pull and reset immediately. Very satisfied with this kit, it's quality, the end results, and the service I received from MCARBO.
Finally got around to installing this kit. Installation was easy with the help of the video. Spend the time sanding and polishing, it is well worth it. Took a state compliant gun with a 10.5 pound trigger down to a smooth 4.5 pound pull. Now I just need to find a way to eliminate the excess trigger movement. Highly recommended
Bought my M&P 45 used, its had some rounds through it. Decided to put the trigger spring kit in and did the polishing also. What difference in trigger feel. Smooth and the break is crisp. Made a big difference in my groups. Only took about an hour to do the whole thing, not bad for the first time I’ve ever done a trigger job myself. Not too light for daily carry either.
My M&P trigger pull was heavy, mushy and completely unsatisfactory. Installed the new kit (it was great fun as well as seriously educational)-which took me about 2 1/2 hours. Now the trigger pull is smooth as silk, breaks cleanly, and best of all significantly tightened my groupings. Thanks guys-brand new and much better pistol for pennies and some time!
Reduced the trigger pull to around 3lbs .. much smoother …the instruction video is very good .. actual install and work .. is not so easy .. the worst is getting the trigger pin thru ..even with the install tool. Also .. work the trigger and slide before you will notice all the benefit .. pulling the pistol apart and back together again needed a break-in .. At least in my pistol. In all .. worth the effort and would recommend. Got 4 star due to some break-in on my pistol .. I was very concerned at first but ok now.
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
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.
So I have the S&W M&P 1.0 9C with the Timney Alpha trigger.... that came in a tad crunchy and not as light as advertised but the Mcarbo springs brough it down to just under 5lbs which I like for my application... I only have the striker spring installed. I'm going to work this in a tad before installing the return spring, striker plunger spring, and sear spring.
no more gritty trigger on my shield plus! what game changer.
Great kit. Used on both my M&P 40 full size and compact. Trigger pull now smoother and way lighter. Sorry I don't have a scale to measure it but it has to be close to if not under 4 lbs.
