A few updates on Kim’s Kimber after some 9000-plus rounds. I saw her this week while in her area for a class and asked to take a look / give it a good cleaning, just prior to her using it at the National Patrol Rifle Conference, which she won two eyars ago. Not "Won the ladies' division", just flat out won.
At this point it has all the original MIM fire control parts, safety and slide stop.
Feedramps need not be mirror polished or even super clean, they just need to have the right geometry….. Kimbers often don’t, this one didn’t and got recut.
The barrel on the inside. I see this on many barrels, mostly and more radical on Kimbers, and yet Kimber factory barrels are very, very accurate. This results from tool pressure while cutting the locking lugs after the bore is done (the flaws correspond to the these cuts on the outside).
Cleaned up it’s not so bad. Anyway these are less than .001 deep.
And, how to get a barrel that clean in just a few swipes: Chore Boy copper pan scrubbers on an Iosso Nylon brush.
Factory barrel is locking up on only one lug, this is typical of all or most brands and actually not much of an issue in .45. However when the time comes for a new barrel on this I will do the three-lug fit as I have done since the late 80’s. All three pull locking duty; again, not a dire necessity in .45 but it helps in terms of safety and especially longevity.
Modified MSH to allow going wider at the bottom. This allows a radical girth reduction—when you grab this Kimber your hand says, “wait, this can’t be a .45”. This was right before I got my first production run done of the MSH-F (fitable). I wanted the forward ledge for a great magwell and I wanted the MSH wider so when I inserted for the ledge I left it wide. Insert is T-slotted in, pinned with a drive screw, and silver soldered. It’s going nowhere.
The FRAG’d MSH with “hips”. Lots of holster wear on this gun but the paint is holding up decently considering that due to timing we decided to just paint over the existing Warrior color and bare steel where the gun had been worked on. I strongly prefer to paint over fresh Parkerizing.
