CW 40 Barrel lands-Accuracy

[spazzwarr]

Hi, I am a new member to this forum. I can see it will be useful and a great place to hang out.

Recently purchased a CW 40 from an older acquaintence who bought it new and put about 15 rounds through it. He was not comfortable with the recoil and slide action. so the gun is basically new. I took it to the range, fired 70 rnds. and could acheive no level of decent acccuracy with a number of different brands of ammo. I returned today and put another 100 rnds. through it. I am a decent shot and own CZ, Tokarev, Glock, P64 and other handguns and get more than satisfactory accuracy with them. I really like this gun and want to use it as my CCW. Any ideas are suggestions?

also, the barrel has two "blemishes" on the lands at 10 and 12 o'clock postions looking in from the muzzle. One has a slight grity feel to it. The other feels ok. Anyone seen this before? Of curse, this may be the reason for my accuracy concern. Could it be NCS tool chatter during manufacturing.

Thanks, spazzwarr

I would slow down your trigger pull and make sure you aren't yanking it. Also, use a bag or a rest and shoot from about 5 yards and see if its you or the gun.

Define level of decent accuracy. Do the blemishes appear to be corrosion or a plating issue and significantly rough?

I have an MK that spent some time on the bottom of Puget Sound (salt water)after the owner dropped it crabbing. Sent it to Kahr for complete go thru and it came back like new except the same original barrel. It looked good. No one could hit a paperplate consistently at 5 ft, it was seriously all over the place.
I replaced the barrel with a new one (no charge) and it's tack driver now.
Upon close magnified observation I could see the polygonal rifling was corroded. Apparently enough to make it a scatter gun.

You could try a little lapping or just more shooting to see if it smooths out.

i serioulsy doubt if the barrel is the issue of your accuracy issues.All the guns you mentioned have a different trigger system than your kahr does. YOu need to put more rounds down range to get used to the loooong trigger system of kahrs and if you feel it is the barrel, then let a good shooter who has had some kahrs try it out to see. Not alibing for kahr either but I just don't think your barrel is the issues.
If in doubt send the barrel back to kahr and let them inspect it..

Welcome to the zoo. (No disrespect to anyone) :)

I pretty much agree with the other posters so far.

I'd soak the barrel in some CLP and then give it a really good brushing first. Dry the barrel out, lube it up as per the lube diagram, take it to the range, bench it and use a steady pull on the trigger. If that doesn't work, send the barrel to Kahr.

Re Accuracy: I was shooting at 10 yrds. using a standard police training silhouette target. 90 rounds fired with 67% actually hitting the silhouette target 16" wide by 23" tall. Grouping ranged from 8' to 14" per 6 round mag. I can get 4" groupings with a Taurus TCP at the same distance and that is partially why I expected better.

The rough area on the land apears to be gritty like fine sandpaper about 3/8" long about 1/2" in from the muzzle.

I have been avoiding sending it back to Khar but it looks like I will now. Thanks to all for your suggestions and advice. I am going to work on my grip with this gun and getting more acquainted with the sight set-up.
