CW45 Long Break In

[Pa Kahr]

Purchased my CW45 about two months ago. As of today have put about 450 rounds through it. The first 350 was tough going. Had at least one stove pipe out of every six rounds fired. This was followed with regular cleaning, but not a complete take down of the slide. So I bit the bullet and disassembled the slide..what a mess! After a good hour of fine cleaning, and I do mean fine, IE looks like new. The gun performed much better.
Have any of you had this same problem? Yes I did a regular cleaning upon purchase. Not a deep cleaning like I ultimately had to do but a good field strip cleaning. I used Winchester, Remington, Federal and UMC Remington flat tip ammo during this LONG break in period. Almost sent it back but since it seems to be behaving after this deep clean I will hold off.
Let me know if any of you have had this same problem, I have not seen any posts regarding this so I thought I would share.

I've got 250 rounds though my CW45. I had one fail to fire during the first 100 rounds (good primer strike but no boom) and one failure to go into battery during the second 100 rounds (pushed slide forward and it fired). The last 50 rounds were flawless but I'll have to gain some more history with the firearm before I'll be comfortable about it's reliability.

BTW, is your guide rod beveled at the end that is inserted into the slide (see my earlier thread)?

evidently kahr is not getting their sloides clean after their machining process. My thoughts are that it is maching oil etc that is just gummed up inside and they are not getting it clean enough. Once spiffy clean that little clean out hole on the bottom of the slide is all you need to use to keep that area clean and ready to go.

2edgesword my guide rod has the bevelled end. Jocko, I was surprised by the amount of metal shavings I have and continue to see on cleaning the CW45. My Ruger had a lot of grease but not nearly the metal shavings. BTW the Ruger had some minor early problems but no problems for over 1300 rounds...

another reason to whern cleaning the gun to just spray every time in that little clean out hole onb the bottom of the slide . Takes 10 seconds at best. Insert nozzle in hole and spray away, fluids will comeout front and back. Then I even pull back the striker and while holding it back I spray directly from the breech face intothe striker channel, witht her striker pulled back anything left will comeouot of that clean out hole. this IMO should part of what one should do when giving his gun a cleaning job. I have never taken my srtriker area apart other than in its very early stages, I installed the 5# striker spring and then even thin I just took off the back plate and pulled the spring. I never took the slide all the way down. Once I realizedf whatthat little hole in the bottom of the sldie was there for, I just spray clean that channel every time I clean the gun..

Probalby not metal shaving ur seeing but brass shaving from the casing, or primer swipe. If u look at the photo that kahr shows in their manual, it shows what we call a primer swipe which kahrs says is OK to see on ur spent rounds, but this swipe could also be dragging back insode the striker channel some of this primer swipe. Just my theory, Ihave 30,000+ rounds through myPM9 and have never had a light striker, nor ever taken down the slide completly either, but that fokker inside is spiffy clean, I am sure of that to..

What cleaner do you use to spray into the hole? And then do you use compressed air to dry the striker channel? Believe me I really do not want to have to take the slide apart every 300 rounds....

I would also like the name of the spray.

FWIW - I (and a whole bunch of others here) use the non-chlorinated 3M brake cleaner from NAPA. About 2 bucks a can when on sale.

Just let the slide sit for a bit. No real need to blow out with compressed air using the 3 M cleaner. It has plenty of power (psi) to get all the cr*p out and will dry on its own.

Is the hole you spray it in on the inside of the slide?

[MW surveyor]

Yes. It is almost the exact size as the extension tube for the spray cleaner. Please see the sticky in the tech section. Or look at your manual.

I just picked up a can of the 3M spray #08880, it works great.

[MW surveyor]

That's the stuff. Works great don't it?

[jocko]
