review-star review-star review-star review-star review-star
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.

After watching the video and reading the reviews I bought the spring kit along with the block, punches and hammer. Cleared off a work space and performed the work in a shallow cardboard box so parts couldn't roll away. Watched the video and kept pausing it as I worked. Took a couple photos after I took the grips off for reference. The Rapide has a mag well flare attached, no need to take the screw out of the bottom, it's dovetailed to the mainspring housing and they come out together. The Rapide also has an ambidextrous safety, so it's slightly different from the video, but it wasn't an issue. Took me more than ten minutes, but less than an hour and cut the trigger pull in half. Took it to the range to function test before I carried it and it performed flawlessly.

Anyone attempting to install this trigger upgrade had better have the patience of Job! The hammer spring and trigger spring are fairly easy to install. The replacement sear spring, however, is another matter. You need THREE HANDS for this job! I became frustrated when I reached this stage of the installation and ended up taking it to a gunsmith to complete the task. EVEN THE GUNSMITH HAD DIFFICULTY INSTALLING THE NEW SEAR SPRING. Unless you're a talented gunsmith, buyer beware!

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.

myrtlebeachsobol January 14, 2022 10:09 PM
Answers
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 .
