Report on my PM45

Discussion in 'Kahr Club' started by Catshooter, Jan 28, 2010.

  1. I love my PM45. I've had to work with it a bit to make it work like it should, even had to send it back to Kahr. They paid both ways, and now it works. Very accurate pistol too.

    One thing I would change about it however is no flush mag. I want both, the regular mag and a flush mag, like the PM9. I emailed Kahr about it. Nice guy emailed my back quickly and said they have no plans to make any. *sigh*

    I tried shortening one of the factory mags but I failed. Stainless steel is sometimes no fun to work with.

    Then the other day on KahrTalk I read a post by vom about using a Colt 1911 mag in his. Ooooo. Lights went on. So I grabbed one of mine, a Springfield Armory seven round blued mag and went to work. Cut it, and spot welded the base back on. Took it out and shot it, nope, the base came of right away.

    So, back to the shop. Thought about solder, but didn't like the idea. So I broke out the oxy/actelene and just welded the base plate to the mag.

    Shot it tonight and it works! Fed great, the only thing it didn't do was lock the slide back as of course the two followers are very different. Here's a pic:



    I did make one small alteration to the pistol, I filed a small notch in the frame to clear the toe of the mag base plate. I wanted flush!

    Thanks for the inspiration vmo, now this fine piece is a pocket piece at last.

    Oh yea, almost forgot, the shortened mag holds six rounds! It's not too crowded either, it still has a little room left, but not enough for another round. Shorter mag, more ammo. Go figure.

    Intersting concept.

    Did you take any steps to keep the heat of the welding process from affecting the spring temper?

    I was thinking of something like sticking a nail through one of the magazine holes to keep the spring away from the heat or something like that.

  3. Cat,
    Very interesting modification; the results look great.
    Actually you can remove the spring and follower by doing something similar to what you describe. You compress the spring and hold it in place with something through one of the magazine holes and in between the spring coils. That removes pressure on the follower and it can be maneuvered out the top of the magazine. Release the spring (best to do this with the top down on your work bench) and remove it out the top.
  4. Caver,

    gb6491 has nailed it for you. That is the way the original 1911 magazines were designed to be disasembled, from the top. The base plates were welded on from the begining.

    But, the feed lips are heat treated, so they have to be protected. I clamped the mag in the jaws of a large vise and let it act as a heat sink.
