Turd Polishing - NYPD K9 *Now With Range Report*

[ScottSouth66]

After doing a polish job on my K40 I've come to the conclusion that the frame and slide ONLY are actually a low chromium content stainless,for corrosion resistance and strength,kinda like a good knife blade,too much chromium helps in rust resistance but diminishes the materials toughness.
The small parts and the barrel appear to be nickle plated carbon steel,judging by the softer nickle color and the fact that if you polish any of those parts too much you will burn through to base metal.

D@mn! That's nice!

Your barrel metal maybe stainless under the nickle plating. I believe the barrels in my PM40's are. I removed a fair amount of material with a rubber abrasive wheel from the end of the ramps that were creaming the magazine followers. Once re-polished, the metal under the plating matches the adjacent polished plated areas and the ramp itself is soft enough to gouge slightly, so I'm betting the barrel is stainless. But, hey, so long as it doesn't rust . . . who cares?!

Anyway . . . thanks for sharing the polished pistol porn!

Scott, that polished slide looks sharp.

I called Kahr today and they verified he frame is just bead blasted with no other finish on it. So, I took some Flitz and cleaned up the dark spots on the frame. It didn't get rid of them but did lighten them up to the point I can live with it. I was careful not to polish too hard so the matte look is still intact.
Some before/after pics:







Before picture of the frame is in my earlier post. Here is after (i still have to figure out what to do with the trigger).



I think it cleaned up nicely and I'm happy with the way it looks now, but that trigger still bothers me. Any ideas of what I can do?

You can pick up a new trigger from Kahr for $15.40.

I don't know how hard it would be to install, but I'd bet a good gunsmith could do it at a fairly low cost.

The biggest hitch in trigger replacement I hear is getting that pounded in pin out . So order a spare pin as well,and heck,might as well get the new return spring for a couple bucks too,since you're going that far.
I'd bet there would be no fitting probs due to the high accuracy of CNC replication. You can also kill that rust at the molecular level and give that frosted/blasted look back by swabbing the surface with some Naval Jelly,or Phosphoric acid from the hardware dept. Just test a small unseen area first,and be sure to neutralize with soap/water afterwards.
Here's the other side btw....

That K40 is making my britches stick out in front.

[jocko]

there is a cure for that anbd just sometimes one has to takemattersin his own hands. Just sayin.

[espresso]

I think it looks a LOT better all cleaned up.
If it were my gun I'd just shoot it.......yeah like I stole it.

[jocko]

proprietary steel????

Kahr Barrel

The Kahr barrel begins its transformation from a solid round billet of high tensile strength proprietary steel, 3 inches in diameter and 30 inches long. In the temperature-controlled environment of the Lothar Walther factory, the barrel stock is gun drilled and rifled to match grade tolerances.

At the Kahr factory, the barrel stock is precisely cut to length and CNC machined. Nearly 75% of the solid steel billet is machined away to produce a single Kahr barrel. This intensive production method, providing the greatest material integrity and tightest tolerances, was chosen to assure the best quality barrel possible


I think kahr barrels are stainless and then nickel plated. Just sayin

If you want to avoid the hassle of replacing the trigger, you should be able to polish the face of the trigger with it in place, starting with 600 grit wet-or-dry production paper and moving to higher numbers until it pleases you.

If you are really careful, you can even use a felt wheel on a Dremel tool with polishing compound, but doing it my hand will give you the best control. I suspect the trigger is stainless, so it should look really nice once you are finished. Even plain carbon steel should look very nice, once it is polished.

We will be looking forward to more pictures, of course.

if it is just polsihing, then indeed some 600+ grit paper cut to fit inside that trgger area will shine that trigger like a diamond in a goats ass. Just sayin

That slide looks nice.

That trigger replacement: Getting the pin out with a punch is the easy work. Getting it back in while keeping everything in place and hammering the pin back in at the same time is more of a challenge. You have to be a bit of a contortionist, be very patient, and be ready for trial and error as well, and think out of the box. Been there and did that. Not for the faint of heart but it is possible. Think 3 times before jumping into it. You've now had your friendly warning. :israel:

Now how would you know..... never mind don't answer that.

So how did I know Tinman had one of these in his file......
