I am slowly researching a replacement ignition kit for my edc: a Kimber compact custom. Nothing wrong with the MIM set currently installed; I just enjoy swapping out parts and like knowing exactly what is in my gun and why. I'm looking for a hammer/sear set that is:
-"drop-in", understanding that nothing truly is. I do hope to have to perform a minimal amount of fitting, as this is one spot on the gun that I know I have to get right.
-I am pursuing reliability over refinement; meaning I would prefer a higher full cock notch on the hammer to ensure engagement with the sear. I don't want some stray particle of dirt or sand to get onto the hook and not allow enough room for the sear to rest. My stock kimber hammer has a 0.025" hammer hook and a poorly finished secondary angle on the sear, so I'm used to and can accept some creep.
- I would like to set it up for a trigger pull weight of 4.5 - 5.5 lbs. This is my ccw gun, and I personally feel more comfortable with stiffer trigger.
To fulfill most of these desires, I'm looking at these three sets:
Cylinder & Slide Professional Kit: Comes with all of the parts pre-tuned to get the heavier trigger pull, but I cannot find any info on the hammer's full cock notch height. http://www.brownells.com/handgun-pa...ing-kits/1911-trigger-pull-kits-prod5502.aspx
Cylinder & Slide Marsoc kit: Only comes with hammer, sear, and disconnector, so I would need to tune my own springs to get my desired pull weight. The hammer is advertised as having a 0.023" full cock notch. The other parts are described as being built to "Marine Corps Specification". Not sure what that means, but I would believe the Marines would similarly value reliability over refinement. http://www.brownells.com/handgun-pa...piece-drop-in-trigger-pull-set-prod27209.aspx
Harrison TR HD-120 Extreme Service: I have heard the most positive ratings on this kit, and the extended discussion on the TR sear on 1911pro.com was fascinating. I believe this would be a good choice, but the hammer hooks are cut to 0.019 - 0.020, which is just a little lower than I wanted. This also comes pre-finished in black ionbond, which is pretty cool. http://www.brownells.com/handgun-pa...me-service-ignition-components-prod27501.aspx
One final option would be to mix and match: I can buy the C&S Marsoc hammer separately from C&S, and then combine it with the TR sear. That might be the best of both worlds, but then I'm not getting a set that was attempted to be tuned ahead of time. I would prefer to get a set that has the hope of not needing much work.
Any experience with these kits out there?
