CW45/P45: Flush fit magazine - UPDATED

[gb6491]

Punted...

Since I couldn't get a modified OM mag to feed well enough for me, I went the other way. I pulled apart one of my 7 round Kahr mags, and cut the bottom off. I modded it to use the removable floor from the Kimber mag. In the end, it looks really decent, and protruded about 1/16 of an inch. I used the Kahr follower, so I'm still at 6+1, but it should be dead on reliable.

Excellent! Would you please post some photos of it and how you modified the magazine? I think many folks would be just as pleased with that.

Here's a couple of pics... Both are Kahr mags, Kahr springs, Kahr Followers, 6 rounds...

When I get a good trip to the range under it, I'll hit it good with a rotary brush to clean it up a bit.

Hey guys great info, my first post. Got my kahr cw45 about a month ago and just did the mod on two mags I ordered from CDNN sports. Both shipped were about $36. For both I just took a little off the top sides, and some off the part in front where it meets with the barrel's feed ramp (enough to where it sits right underneath the ramp). First gun so pardon any wrong terminology.

Mec-Gar Officers 45acp 6rd Blue MGCO4506 1 13.99

MetalForm Officers 45acp 7rd Blue MET45S290 1 9.99

The Mec-Gar holds 6, seems better built, and holds the slide open after I eject the last round. The Metalform holds 7 but doesn't hold the slide open on the last bullet unless I push the magazine in a little tighter, this is enough to raise the slide stop lever on the inside. I'm going to try bending that little part up a little and see if it does it then. I'm going to the range to test both mags sometime this week.

My last mag experiment is a winner. I'll keep it!

Is this the one you're referring to? This is whole different approach (removing the floor plate) How'd you do it? Will you post some pics here?

I bought a Kahr mag. I put it in the pistol, and marked with a sharpie, about 1/8 below the grip. I cut the mag bottom off with a Dremel wheel. I looked at how the bottom of the Kimber mag was shaped, and cut the Kahr mag to look about the same. This ended the easy part.

I then heated the bottom of the mag with a torch, and started to bend it with small "gator nose" pliers. After I got pretty close to the bends that I saw on the Kimber, I stopped and used a Dremel wheel again, to trim things up. After that, I put the two floor pieces in place on the mag, and squeezed it a bit in a padded vice. I heated up the whole thing, and started tapping the bends to a square right angle, and into the slots on the Kimber floor. Then I scrubbed it up good, and put it all back together. Somehow, got it pretty well right on the first try.

Now that I know it works, I'll put a wire wheel into the Dremel, and clean it up good...

Yes, it is still removable.

Wow, nice work and thanks for elaborating. I might need to add a blow torch to my list here soon in addition to the various files mentioned previously in this thread. lol
Greg,
Have you ever considered this approach?
What is your opinion of doing it this way compared to the way you've done it?
It just seems to me that changing out the floorplate would be the best solution with the least room for error. I'd imagine the feeding end of the magazine must have precise edges/angles to allow for proper feeding.
