1) Anyone have trouble with cor-bon 115 +P feeding in their CW9?

Unlike most of the reports here, my CW9 has fired approximately 700 rounds without a misfeed (including "break in"). I've fired 7 or 8 different 115 FMJs, and 3 115 JHPs. I had two misfeed recently. One right after the other. You guessed it, the above mentioned Cor-bon.

I'm aware that guns are individual creatures, but I'm curious if anyone else has noticed a problem. The bullets are too expensive to do extensive testing, so my sample is only 2 failures in 15 rounds. For every single other round I've fired it's 0 failures in 30-300 rounds.

The Cor-bon appears to work great in my G17 (0 failures in 30 rounds). Perhaps the short stubby HP and gigantic cavity don't jive with the CW9.

2a) Newbie update - Customer service

Love the gun, but I'm EXTREMELY unimpressed with Kahr quality control and customer service.

Had to fight tooth and nail, and was ping-ponged between Trijicon and Kahr Cust Serv, to get the defective night sight replaced. Several hours of trouble. In the end it was taken care of.

During the night sight fiasco, I brought up the sticky no-drop OG 7 round mag problem. They shipped a brand new mag to me. It's stickier than the factory original. I measured the mags, and they bulge at the bend for the feed lips by 0.02". The two Kahr factory 8 rounders I have do not bulge and drop free like butter.

In summary, they need to get the Quality Control and Customer Service lads together and give them a stern talking too.

2b) Newbie update - Gun performance

What's not to love. It's on par with my G17 in accuracy. It's comfy. It's reliable. Wife really likes it.

Minor (and predictable) downsides are...

I'll post chrony data if anyone is interested, but in summary the Kahr is 5-10% slower than the glock in all my chronograph tests. +P JHP tended to be closer than "bulk" FMJ (5% and 8% respectively). At least in my gun, that means you aren't sacrificing as much power with self defense loads for the compact vs full size gun.

The crazy long trigger pull/reset is VERY slow for fast shooting. I find it's actually slow enough to affect speed at relatively long ranges (e.g. when target acquisition would normally take much longer than the trigger sequence)

Recoil is friskier than I thought at first. After shooting it from a rest side by side with the G17, I realize it's pretty saucy. By no means painful or scary, but I'm guessing my upcoming speed drill comparison will be considerably slower than the G17 or my buddies Sig P6. Not really surprising though.

Anyway, just thought I'd update. I don't regret adding the CW9 to my collection one bit. It's a fine pistol.

If anyone is interested in my chrony tests, just holler and I'll post it up. I intended to do some more testing, but my wife shot my chrony with the CW9. Waiting on a replacement box.:7:

G17 pretty big gun to be using to compare to a cw9, IMO. The G17 should feel alot better. It has a completley different trigger system than a kahr BY DESIGN. Kahrs trigger system is 3/8" lopng and super smooth. It is there by DESIGN.. Again I wouldnot use the glocks as a comparison to kahrs, they are two totallay different guns IMO.

U should not have issues with corbon, but if it belches wtih 115 corbon, then indeed don't use it. To many good other defense rounds out there to choose from. I shoot 115 wwb fmj all day long in my kahrs and have no issues. Ihae never shot 115 corbon but I carry their 100 grain power ball and it works perfect. Moist seem to shoot the 124 gold dots..

Didn't mean to imply the CW would stack against a G17. It weighs 2/3 as much and is 3/4 as long. I was simply using the G17 as a control since I have extensive data on the G17, and it's arguably the most likely gun to also be owned/experienced by someone on this forum.

I'm new, and haven't searched, but why is it designed that way? If it was 1/4" shorter it would be incredibly wicked, and not appreciably slower or longer than a glock/XD/Taurus/Smith "plastic pistol" trigger. Is it "safety"?


U should not have issues with corbon

From the scarcity of google reports, I assumed the same. The ammo is so expensive though, I thought maybe the Kahr forums would be the place to poll for my particular situation. The average "youtuber" might not have a Kahr and some Cor-bon.

REALLY? take a poll and find out.

might have something to do with cocking the striking mechanism. id get into it but wont. search function is your friend.

The average "youtuber" might not have a Kahr and some Cor-bon.the average "youtuber" who owns a kahr probably has figured out that "all guns", regardless of manufacturer, may or may not function with a particular round and avoid those rounds for defense.

Exactly. That's why I came here for data.

The Corbon DPX runs very well in my K9

I think its the best ammo in 9mm avail for JHP

Never had a problem with my CW9 with any factory or my reloads in the last 1500 rounds or so. Gun just goes bang every time I pull the trigger.

HST 147 grain work in my CW9.

I don't have a Glock, don't want one either. But hey it's your gun! Enjoy.

Go to the tech section I think? Theres a thread there about doing a little pinch on the top end of those mags that will make them drop. It's easy, fast and a few here have had great success with it.
I don't have time right now but I will look for it for you after a bit. SWMBO has given me my running orders for the day and it ain't pretty.

Far as the trigger reset, it sucks. Ain't no getting around that but for what it was designed for I think it's perfect. I know many officers and shooter who are obsessed with trigger reset and the Kahr will just never pass muster for them. It is what it is and many love it just for that reason.

Glad you found us.
