View Full Version : K9 compensated barrel

I see on the Kahr web site that they offer a "compensated" barrel for the K9. If anyone has any experience with this barrel I'd love to hear what they like or dislike. Wonder too if the barrel has polygonal rifling? Length?

I'm not sure I'd need one but this stimulus is burning a hole in my pocket. Also, can't think of any other industry I rather stimulate.

I think Wynn has one of those, pretty sure he did anyhow, hopefully he'll be along.

I read a post on here about those, apparently the owner was very happy with muzzle rise reduction. I have considered such a barrel but I am a bit worried it might be damaged hanging out beyond the slide. Still a Luger or P38 barrel really "sticks out" and those did fine in the world wars and many conflicts beyond.

I would have to get custom-made holsters though as the barrel would go bast the bottom of the holster.

Got one last year. Not a big difference with recoil but wasn't too thrilled with accuracy. At 7 yards I was shooting 2 feet below POA. To correct this I think an adjustable rear sight is required because

the sight radius has changed. Would like to hear if somebody has a different idea or maybe point me where to find one. Thanks.

I searched and found multiple discussions re. Kahr's ported barrel. Nothing so compelling that would make me think I need one, darn it. I really appreciated Wynn's freeze frame photos of his comped Kahr. I was amazed at the photo showing his pistol in AB.

I was amused at one posters suggestion that the comped barrel would make a dandy bottle opener.

I'll move on to some threads and photos on wood grips. I can be stimulated by that, too.

PS new K9 now at 350 and counting. I ran it up to 350 from 250 without cleaning just to see. Had one failure to feed around, probably, round 340 or so. Can't blame the pistol, shooting pretty grubby Bullseye powder reloads. I love this pistol.

Good looking wood grips! Thank you for the heads-up on the poa issue with the ported barrel. Two feet below center of mass would instantly make the bad guy a soprano.

Thanks for the review! That settles it, I won't be getting one of these barrels!

I don't see any reason the sight radius would be changed, the slide is the same. Apparently sights just aren't regulated for that barrel or it's defective. Would make a dandy bottle opener.

I had my K40 Magna Ported, I prefer that look over the barrel sticking out the front. If it stuck out to accept a suppressor, might be able to live with it. Course I'd never spend the money or jump through the hoops to get a can.

Years ago we recovered a MK9 that fell off a deputies belt while he was out crabbing in puget sound. He had a GPS and marked where he was at. Out dept had a couple divers and they went out and found it in no time, still in it's clip on holster. Went from the salt water right into a bucket of outdrive oil. Cleaned it all up and thought just to be safe we'd send it to Kahr with the full disclosure for inspection. They replaced all the springs and small parts, came back in a new box with a couple new mags looking like new. (No Charge).

The deputy felt so stupid that he didn't want the gun back, it became a pass around gun for awhile until a detective laid claim to it, most all the grips I've made for MK were with that gun.
Anyhow nobody cared for it as they said it wasn't accurate. 4 or 5 guys shot it over a period of time and said it just didn't hit. So I ended up with it, took it out to a place in the woods we used to be able to shoot at and hung a paper plate.
Started at about 7 yards and I could not hit the plate, moved to 5 then up to about 3 yards.
I finally just winged an edge and thought, oh the sights are just off. So I held to allow and no hits. Then I hit just the edge of the opposite side of the plate.
Long story short, the salt water had apparently corroded or defiled the polygonal rifling. It was all over the place. I got hold of Kahr again with full disclosure and they sent me a barrel. Thing was an absolute tack driver, then everybody wanted it.

The end.

Got it on sale before Christmas for something like $79. Maybe the barrel is bad? The original one is dead on. So far not a big loss, just satisfied my curiosity. Or maybe should I contact Kahr's service????

Does it shoot groups two feet low? Or kind of all over.

The sight radius didn't change, but something did. Eli knows his bargain ported barrel shoots different from his oem barrel. He wants to fix the issue by installing an adjustable rear sight. To make his k9 shoot point of aim at 7yds with his ported barrel he would have to crank up the adjustment on his new sight to a little bit over 1.5 inches. That would look funny and probably snag on his clothing when drawing the gun.

To do more tests we need to wait until next month when the local range will open up. I am curious too and mad at myself why I didn't do a thorough test like Bawanna did with his MK9. I guess I was totally disappointed expecting different results.

Raise the rear sight 1.5 inches and the Star Ship Enterprise should be very concerned. I suspect a shorter front sight and a slightly taller rear sight are in order if in fact it shoots good groups.
The MK I mentioned was all over the place. A foot right, then a foot left and most no idea where they went, didn't have a big enough target to tell.
Also curious is that is polygonal or conventional rifling, not that it matters, still could be something wrong.

Cool story Bawanna,thanks for sharing that!

Too the picture of both barrels - the ported one is on the left and my original one on the right. It appears to me that both have polygonal rifling. Once I do more shooting I'll post result. Stay safe!
