PM9 Mag Base Plate Mod

[Tilos]

I got tired of the (not) flush metal mag base plate biting my pinkie.

I modified the (not) grip extending base plate from the 7rd mag that comes with the PM9 to fill the mag/grip gap on the 6rd mag.

What do you think?

Looks good. I thought that I was the only retentive person out there. I filed, sanded, then buffed out the corners on mine, better, but still hated the gap. After three tries, I found the right size O ring and stretched it on. No gap, no sharp edges. The O ring smaller broke, the one bigger messed up the funtioning. I added a finger rest mag base to an order, and it is flush, but adds a bit of height. Today I received anouther standard, "flush" six round mag, and a Mitch Rosen pocket holster for my P380. I am still not sure if I like the finger rest base, but at least now I have a choice.

4T5Guy:
Thanks,

A CW9 mag base plate will work, is a lot less cutting, an easier fit, and can be bought seperately online from Kahr.
I did sand off that little ridge on the front of the CW9 base though.
The down side of this is added height, but it can be sanded off.

Here you go:

There was someone on this forum who modded his pm9 6 round mag base. I think he took off the base plate, then filed / cut a little off the magazine, then re-installed the baseplate. I think? Sound off if your reading! He had pictures of his work and it looked awesome.

I just bought the polymer base plate from Kahr. It will snap in with some pressure as is from the factory but I sanded mine down a bit because I didn't want there to be any issues with it seating. There are pics of my gun in the "newbie with PM9-why no sticky's" thread.

Swat dude:
Yes, function over fashion is best...modify for function.
I have also noticed the front round edge of the magwell has a sharp edge that can catch the mag during insertion.
Both sides and the rear of the mag well has a generous bevel, as molded, but not the front.
A small radius with a needle handled file is all that's needed to correct this minor oversite and improve mag changes.
Swat dude, I've read your posts and recall your gun has been detailed and may already had this "improvement".

This subject maybe worthy of a separate thread rather than buried way down here.

Just sayin'

Does it seat properly in your PM-9?

[deadhead1971]

It's a tight fit. I may have to sand down the top part--probably the same issues you had. Mine seats but I have to make sure I hear that "click."

I have shot with the base plate on so with the tight fit, there are no feeding issues.

Same here but I sanded the "lip" with my dremel. I took 10 minutes if that.

That Polymer Magazine Base Kit is nothing more than the CW9 base plate that I also mentioned in response to 4T5Guy.

FYI:
I received some Pearce Grip Extensions today and quickly found out they do not fill the mag/grip gap.

Now I just need to buy an 8rd mag to try one of these:

I've been curious about those for a while, it would be great if you can post a picture when you put them on.
If they fill the gap I'll probably get them.

Also - anyone have a pic of the Pearce grip extension on the gun?

Here you go. Notice the gap.

My A&G Spacer should arrive today or Monday. It is designed to extend the grip down to cover the gap of extended mags. Here's a pic of it on an XD.
