Kahr Modification...

[CJB]

I'm a bit hesitant to bring this up, but I've been working on a series of small modifications to the PM45 that ought to work out ok for other Kahrs.

Backstory - Part of John Moses' genius was how he invented military guns that contained all that was needed to totally disassemble the gun, as parts of the gun. The hammer strut became a push pun, the magazine base became a pin pusher and mainspring plug depressor, the sear spring became a magazine catch lock tool, etc etc.

The Kahr is a really nice design, but I've got a few little tricks.

Trick #1 - modify rear plate on the slide to allow depression of the striker spring guide.

Trick #2 - new striker spring guide made from stainless steel.

Trick #3 - Stainless steel magazine baseplate catch with long protruding Torx head, and shallow Torx head to allow depression of striker spring guide and allow dis-assembly of frame.

The slide stop can already be used to dis-assemble the magazine. By using the base plate catch along with the end of the magazine spring, you can totally disassemble the top end, since now the new rear plate allows the spring guide to be depressed. The magazine spring perfectly fits and depresses the ejector side of things. By using the base plate catch you can remove both Torx screws in the frame, and press out the trigger pivot.

Anyway... there ya go, original thinking and Sunday morning coffee. DD of course

Mmmm. Interesting.

I understand his concept and actually love it. I set up my only 1911 that way. The gun with mag is all you need to completly strip it. I even built a milling cutter to cut the grip screw slots the same width as the toe of the mag and also the same radius. So the screw slots are round bottomed to match the mag toe.

The rest was pretty easy.

Can you post some pics of what you're describing? The Kahr design doesn't really lend itself to the idea, but it's a whole lot easier that a revolver.

#2 baffles me. stainless, why, never seen one yet rust, not sure if they are coated or what the material is, being wolffs makes um, and that istheir living, I would think if stainless was the way to go, they would offer it.

Why stainless? Because the plastic might not hold up to being pressed (it might, dunno), and because I dont have any titanium on hand!!!

I'll post some illustrations on the concept when I get back to my own computer. The "hard part" is those #@#$ torx fittings, which would be a breeze with MIM, but I'm not about to invest in a MIM sendout - although Kahr might!

Basically, the inner catch of the mag becomes a tool. Other pistol parts are also used as tools. The slide stop gets a small hole drilled into it, to allow pressing the guide out of the way of its recess. Very simple stuff. Use the mag spring and guide depressor to remove the rear plate...

oops I missed that, I was thinking striker spring, My bad!!! I see alot of polymer recoil rods and really never hear of them breaking kand this striker spring rod guide gets very little awkward pressure . No doubt this is a cost saving in polymer over any metal striker spring guide rod. I do have one in my parts box for some reason or another..

#@#$ what number torx fitting is that, my book of torx parts doesn't show it..!!!!

I'm stuck at the GF's house here... till late. She'll be in from work, then I can vamoose, but looks for conceptual diagrams after work Monday.

I had another thought about the dual recoil spring.... Been looking at it, and looking, and thinking... why was it made that way? The thing that comes back to me every time is so its impossible to assemble without the inner spring. That button on the end has no function other than to keep the inner spring captive. If you really examine it... it touches nothing while the gun is assembled, and ... well... thats that. So now I've got an idea... which I'm sure Wolff already has... but it could be done with two springs, the two rods, but without the button on the end, making the springs individually replaceable and not require the replacement of both guides at the same time.
