Trigger Return Spring for Kimber Micro 9 Pistols

They do not come with written instructions. We have an install video below the listing that will guide you through the install. The kimber does not need the press to get the trigger pin out like the sig 938 in the video, you can punch the pin out with a 1/16 punch on the kimber. The rest of the install is the same as both guns are basically clones of the colt pony.

Yes they share a trigger return spring, I need to get that added to the listing thank you for noting that.

That could be slide spring pressure or ammo, certain bullet shapes do have issue loading in the short barrel actions sometimes. I would try another brand or two of ammo before I start trying to alter parts if you do not have but one box of ammo through it. Typically when we have issues like this is 1: bullet shape/case size 2: use of the slide lock lever to release it rather than pulling it back to stop 3: feed ramp 4: return spring rate Since your having better luck with the slide lock lever when you release I would say try a couple different brands of ammo then look at increasing the spring rate.

Altering the sear and hammer is really the only way to get a lighter pull on these due to the SA design, altering the trigger return spring rate will induce reset issues and dropping the hammer spring rate will create misfires with hard primers. Altering either will not make a notable rate change in the pull.

It is slightly stronger than the spring used for kimber.
