Heavy Trigger Pull on Kimber's Micro 9

Howdy, Everyone!

I’d like to share with y’all some issues I’ve discovered with the Kimber Micro 9. This is a superlatively accurate, powerful, and concealable little gun, relatively comfortable to shoot, with excellent sights and recoil management. However….

This tale begins with an article by Ed Head entitled “The Bane Drill” (NRA Shooting Illustrated, October 2016). Briefly, the author exhorts us to seek precision accuracy from our personal defense weapons by practicing to achieve five “head” shots on a 6” x 6” target at 25 yards, and five torso shots on a 10” x 10” target at 50 yards. Now, in the hands of a competent shooter, the Kimber Micro 9 is perfectly capable of accomplishing this even when fired from a modified Weaver stance. The problem (and my primary issue with the Micro 9) is the weapon’s exceptionally heavy trigger pull, which makes aimed rapid fire extremely difficult, seriously constraining the weapon’s utility in most “active shooter” scenarios.

Thus began my search for a means of reducing the 8.47 lb. pull of my Micro 9. The first call, to Kimber, disclosed that the company did not provide trigger work on any of its Micros. The second call, to a renowned custom smithing company in Louisiana, revealed that because the Micro 9 was not truly a scaled-down 1911, that company could not offer a trigger job. The company’s agent, however, recommended that I contact Cylinder & Slide for one of its drop-in hammer kits. This I did, receiving the following almost immediate and very detailed reply, which I believe you will find of interest:

“[Company X’s agent] must have thought that the Micro 9 is a 1911 design and one of our 1911 drop-in hammer sets would work in it. The Micro 9 is a scaled-up copy of the Colt Mustang 380. We do not offer a drop-in hammer set for the Colt 380 family of pistols or the scaled up 9mm versions. Due to the nature of the Colt 380 design, the weight of the hammer spring needs to be increased significantly in the 9mm version to keep slide velocities reasonable. In addition, when scaling the pistol up for the 9mm cartridge, the engineers left the sear pin the same diameter as the 380 version. Due to these two conditions we will not perform trigger work on the 9mm Colt 380 pistols (SIG 938 or Kimber Micro 9). Sorry we can’t help you on this one, but thank you for thinking of us for your custom handgun needs. Regards, C&S”

So, Foax, the long and short of it is that you are unlikely to find a means for safely reducing the trigger pulls of your Micro 9s. Of course, if you try, you will absolutely void the firearm’s warranty. (Then again, the Micro 9’s warranty itself is good only for 12 months from date of purchase.)

Anyway, I’m up for your suggestions — any takers?

C&S are world class gunsmiths so I'd tend to take their word for it.

You might get a second opinion from Frank Glenn.
He's a Master pistolsmith. He does factory level work on Colt revolvers so he's knows what he's doing.

If he says "No", then you're probably down to buying a different pistol.

Of course you could also ask Clarke and Wilson for an opinion.
