Well, I still need an 8rd mag! I guess I can slip it on my 6rd and fake it. Somebody must have an 8rd for a Kahr 9mm. Kahr states the K9 mag fits all Kahr 9mm.

Who would know

I would! But I will and spill the beans at the same time.

You can use these 8-round magazines. The extended grip model (K920G) is good for the range or a reload carry... friendlier base... not sharp or "pokey" as the flush metal ones or the regular plastic ones (K920) are.

You'll have the magazine tube space above the base, but 8+1 capacity.

I think it would be optimum to have something for the 6 rounder IN BETWEEN the Pearce and the A&G. I have a Pearce for my XD and it is just TOO long - nice, but unecessary length unless you have gorilla hands. The A&G looks a bit short. Here is where I think the Keltec PF9 gets it right.

A #2 mill bastard file can change that!

Yes - but it would look like a bastard.

Received the A&G Grip Extender and found it is for the 7rd mag, not the 8. It looks a lot better than without but is not perfect. For those of us who are a bit overzealous it is worth the $13 to buy.

It does make the grip feel full sized, and while I'll carry the 7rd with grip extenders as spare mags, I will carry the 6rd flush in the holster.

PS: A little careful edge work on the spacer may make a difference in fit.

Here are the pics:

This is the 7rd without the grip extender.


This is with the grip extender and the mag pulled down against the stop.


This is with the grip extender and the mag pushed up snug.


This is with the grip extender and the Hogue Grip pulled down like I'll carry it. Note it does NOT interfere with mag changes.


This an end view to show it's not perfect but not too bad.

OldLincoln: Thanks for the Pics, Questions

Does that grip extender come with it's own base plate?

Do the thing the top of the grip extender could be modified to better match the gun grip and a spacer added between the extender and base plate?

It looks like a better place to start than with nothing.

Thanks for buying one to show us what it looks like.

kahrbrian: or bastarded

[OldLincoln]

Yes it comes with the base plate that fits perfectly recessed into the bottom of the extension.

I think the top can be feathered somewhat but there's a balance between taking some off the top and creating a larger gap. I intend to try mine in a few days but I'm not a craftsman.

I agree it does look better, but as pointed out by another, it will never look like a P9 so why didn't I get one to begin with. I could argue that the P9 doesn't come with a 3" barrel.

The other point for me is my 7rd mags will always be spares so what should I care what they look like. I guess I'm doing it just because I have too much time on my hands.

So I ordered a couple of CW9 base plates for my PM9 mags. I like they way the look when installed, but they slide off the magazine tube with the slightest pressure. I didn't think about ordering the polymer base locks when I ordered the base plates. Can this problem be remedied by getting a couple of the polymer base locks and using them in place of the metal base locks on the original magazines?

[wyntrout]

Ljutic, will those magazines seat fully and lock in place with the plastic base plates?? IF they do, then I would think that the base locks would do the trick. All they do is lock the base plates in place. I find it hard to believe that the plastic base plates will allow full insertion... without modification... of the magazines. I don't remember if I tried the plastic bases from my K9 on the PM9 6-round magazines. I just did, but they wouldn't allow full insertion and locking in place of the regular flush-fitting magazines. I'm not sure that I could remove enough material to make them fit without compromising the strength and reliability of those plastic base plates with the flush-fitting magazines.

The CW9 base plates that I received today will allow the mag to fully lock up. I tried it on two different mags and they both worked fine with and without ammo. Test firing will be needed to assure they will work properly. Of course that's after I order a pair of the poly base locks and get them installed. Oh well, at least the orders ship quickly.

Been there, done that...they work with the plastic plate.
And Kahr lists and sells them as a set, base plate and locking plate thingie.
