CW40/Burnt Bronze

[KahrBo]

Bo here, again-

I'm looking at this particular model, but want to be able to have a 9mm barrel to convert it over, in case of ammo cross-need. Called Kahr customer service and they said it 'can't be done'. I personally think any 9 can be made into a .40 or vice-versa, with a new barrel and mag change. Your opinions? :biggrin1:

Maybe, maybe not, you may also need to change the extractor and/or the ejector. And the outside barrel dimensions need to be the same.

40 to 9 can be done in some guns (Glock comes to mind) with a conversion barrel. The conversion barrels have an outside diameter that matches the .40 and are machined to correctly fit the breech end of the 40 slide. My G27 works fine with a Lone Wolf 40-9 conversion barrel with the .40 extractor and ejector in place. I didn't have any issues using 9mm in the .40 mags either Still this is just for range use, I wouldn't carry it for self-defense.

9 to 40 is a no-go with just a barrel swap in my G19: the breech face is not wide enough for the 40 case.

I was able to convert a CM9 to 40 using a complete PM40 top end (http://www.kahrtalk.com/showthread.php?19656-Modifed-Customized-Bubba-d-my-CM9-*UPDATED*/page4) and magazines, but there are some considerations that have to be met when doing this (most importantly, the barrel lugs have to be the same style).

Generally, conversion barrels work like this. You can only go down in cal. 40 to 9mm with a conversion barrel.(or 40 to.357 Sig)

You can not go up in cal. The 9mm slide would have too small a hole to take the larger .40 barrel.
(Technically, you could go up assuming the 9mm and .40 frames were exactly the same if, you got a whole new 40 slide assembly,barrel, ejector,mag.etc. I don't have a Kahr .40 so I don't know if Kahr frames are the same, but the listed width of 9mm and 40 Kahrs are different so that makes me think they would not be the same???.)
Edit: I see that Greg says above that he did it, so I guess the Kahr frames are the same.

All that said, I have never seen or heard of Kahr conversion barrels being available.

So I would say they were correct in telling you you won't be able to do it.(.40 to 9mm) But not because it "can't be done" just that nobody that I know of makes Kahr 40 to 9mm conversion barrels.

UPDATE: Did a bit of searching and found this thread on the subject, concerning the Glock. There are a wide variety of opinions about it (yes, I realize this is a Glock thread, not a Kahr one) over there. Some have done the .40 to 9mm change, with no issues. That seems to be the consensus from those who've actually done so, hands on. Most of the 'can't be done' folks are falling into the 'haven't tried' category, naturally.

The info on the Lone Wolf site backs up the 'pro' guys (at least of Glocks) too: ;)

FURTHER: Found this on an S&W site, which at least backs up my original assertion about going from 9 to .40, but (again) that's not a Kahr...

ANOTHER piece of information on the Glock Store site, showing conversions going either way. :amflag:

G26 - Replaces existing factory G26 slides and also will allow you to easily convert your current production G27,33 frames to 9mm.


G27 - Replaces existing factory G27 slides and also will easily convert current production G26 frames to fire 40 S&W and/or 357 Sig.

Yes, but these are slide and barrel swaps: IE, if you have a G26 and want to convert it to 40 or 357 you'll need the G27 slide they sell and the appropriate barrel. The G26/27/33 use the same size frame.

I have a complete G26 upper that I now use instead of the conversion barrel on my G27. I paid $250 for that upper LNIB. You can find complete uppers in the $350-380 range on auction sites these days. It'll run you about that (or a little more) piecing together one with an aftermarket slide (barrel/internals/sights).
Here's my G27 with the 9mm and .22LR top ends:

Nice. Looks like you got plenty of magazines too. Nice package.

Agreed, that is one well accessorized Glock !:cool: Only thing missing is some GAP floor plates. When I carry a flush 10rd'er in my G26 it has a GAP floor plate on it.

AFAIKT the Kahr 9mm and 40cal have different internal sizes.

This is not as easy as finding a worn out ex-Chicken Ranch gal, going down to the supermarket, getting a 10lb ham, cutting out the bone, and using the rest as a shim!

LOL... That is one way to explain it, but I was trying to not be so technical with my answer :D

[hardluk1]

karbo why don't you go ahead and buy a 9mm kahr Then you get some steel and a mil and try to make a 40sw work. Might be better off to start with a 40 as atleast you may not have to recut the breach face and change extractor extractor and but you will have barrel size issues to deal with at both ends .


9mm + or - a th's, muzzle dia, .530 , breach face cut .416
40sw + or - a th's , muzzle dia .547 , breach face cut . 440.

I'll be glad to buy a proven and tested 9mm conversion kit for a 40sw. No interest in milling on my 9mm to make it work for both a 9mm and 40.

Let us know how it works out. If your a aero space machinist looking for a little side business go for it. That's what is going on with EWKarms for dan Wesson revolver owners .

Great pic's.
