Just do it , works beautifully

Took me about 1 hour a little bit of frustration. However, overall went very smooth. I. Also changed out the recoil spring, I went and shot 100 rounds clearly a softening of the recoil. Which was always a problem with the Kimber micron. Accuracy improved dramatically with the softer trigger pull. Ps...first time I completely took apart any gun and it went great.
Great aTrigger Kit!

my micro 9 stainless was made in 2020 . love the gun but the pull was really heavy. i didn't shoot it much and didn't carry it at all. this kit reduced trigger pull iby at least half if not a little more and made such an improvement that i'm carrying my micro 9 everyday now. Thank you!
AWESOME!
review-star review-star review-star review-star review-star
It improved my groups tremendously. My new Kimber Micro 9 was pulling out of the box average of 7.6. I would struggle to hit anything with that trigger. Now it pulls around 3.5 and I am keeping this awesome bang, bang!

Not to difficult to install thanks to the Mcarbo video as well.

I was able to put in the Kimber Micro 9 3 spring kit in under an hour. I also put in the Galloway 22lb flat recoil spring and trigger return spring. M-Carbo rules I got 3.2 lb and no FTL after 60 115 grain rounds. I put the M-Carbo flat trigger and other stuff on my Sig P365 X Macro Comp and the same results. Great products, great install videos and fast shipping. IF YOU HAVE A KIMBER MICRO 9 YOU HAVE TO GET THE M-CARBO SPRING UPGRADE KIT.....

A good trigger made great

4lb 1oz. This trigger kit was an excellent modification for my Kimber Micro 9 Rapide Dawn. The stock trigger was a little heavy for me. The MCARBO kit fixed that and I feel that my Micro 9 feel great.

This is a DIY kit, but I decided to have the specialists at MCARBO polish the internal parts and complete the installation.

Note: I also purchased MCARBO’s new Kimber Micro 9 Extra Power Recoil Spring. The combination of the two is AMAZING.

A very nice set indeed; the instructions were very well done and accurate. The set reduced the trigger pull by about half - still leaving a solid trigger wall. The sear spring was less than a joy to install as are all sear springs on any 1911 based firearms. I found it easier to install the sear with a deep grip on the sear with needle nose pliers with the pistol laying on its side rather than trying to stand it upright on the magazine well. All in all a relatively easy assembly even with the fiddle sear and sear spring. Well done Brothers!

I am not a gunsmith but managed to put all 3 springs in in about an hour. ( use the u-tube video)They work as advertised lowering the trigger pull by about half. I do not have a devise to measure just going off how it feels. First 2 springs went in in about 10 minutes. Sear spring however needed patience and about 4 tries until I got it right. Trigger is crisp. I also installed a new main spring which is heavier than factory spring. I went to range and gun preformed flawlessly both with 115 grain and 124 grain FMJ. I just wish I could have gotten main spring from Mcarbo also as it would have saved me on 2 shipping costs. I recommend this product to anyone that wants to lower trigger poundage for their micro 9.

Question:
I purchased the kit for my Kimber Micro and did the install following he video. All was easy and pretty straightforward and all the system checks worked. Went to the range to try it out and after racking the round and depressing the trigger it won’t fire. The hammer drops but the pin obviously isn’t hitting the primer. Doesn’t appear to be a light strike and this is a brand new unfired weapon. Where’d I go wrong? It’s got to be something simple.

No, this spring kit will not affect the force required to pull the slide back. Unfortunately we do not offer any lighter recoil springs for this firearm. Each model is slightly different, but lightening a recoil spring too much could cause the slide to not cycle properly.

Hey my wife just got the black ice micro 9 and I just ordered the spring kit. I just pulled the pistol apart and you don’t need to remove the ambi safety to install this kit just draw the safety back all the way to remove the hammer. Also you don’t need to remove the t10 screw on the mag extension just remove the pin on the hammer spring housing .
