New CW45....and a problem already...and back from the shop

Back from shop and says:

Replaced barrel, slide stop reworked, and reworked trigger bar.

Had a couple of light primer strikes out of the first magazine, but so far, so good




Put a bunch of rounds through my new CW45 today and having an issue that I have never had in any of my other guns.

Using the factory magazine that came with it, I find that the last round in the magazine chambers just fine, but the gun is not cocked. Not just one time, but every time I tried it, the same issue. :mad:

Any suggestions since it is the weekend and customer service is offline?

[Bawanna]

Only the last round every time?

[kerby9mm]

That seems to be an impossibility that only the last round would not reset the striker. I would think it is a coincidence. What could be different from #4 or #5 to make #6 special like that

[OldLincoln]

To be very clear.... when you shoot the next to last round of the mag, the recoil operates the slide back and forth which chambers the last round, but when you pull the trigger as far as it goes, nothing happens. No click, no feel of something, it just smoothly and lightly goes all the way to the back of the trigger guard.

Is this what you are experiencing? It does sound odd, so bear with us to understand what clues you have.

[OldLincoln]

I know it's not funny but then I'm a bit off anyway.... If Bawanna or Jocko reported this I'd reply that the spring wound down and they need to wind it tighter, or change the battery, or some other silly reply. It's just I have not read of this happening until now and we do kid a lot around this campfire.

I believe what you are reporting so please don't take umbrance for my comment.

[Bawanna]

I'm sure stuck on this one. Don't seem possible. Only the last round.

[JFootin]

What a strange occurence I don't have a clue how the gun could do that. :001_huh: A couple of more knowledgeable members than me have chimed in here so far. Maybe Greg, our resident wizard of DIY fixes and enhancements, can enlighten us. There are several other good minds that can chime in here, too. This one is a real Sherlock Holmes mystery.

[kerby9mm]

Have you tried dry firing and re racking multiple times to see if you can get the striker to not reset?

[rwehnau]

Yes it the last round in the magazine every time.

Tried with a full magazine and then tried it only two rounds.

It chambers but does not recock.

No indication at all that it is going to fire and trigger comes all the way back.

Damnest thing I have ever had happen also.

[KMA]

I do not say that it could not happen, but I do not understand how it could be possible. Can you please be more specific and tell exactly what happens after you shoot the next last round?

[rwehnau]

Initially i thought that the slide was not locking back after the last round fired because NO BANG and trigger came all the way back with no resistanace or any indication that it was cocked.

When I cycled the slide, out comes an unfired round with a perfect primer.

Same thing every time last round only.

[OldLincoln]

I ask you to try giving the back of the slide a solid wack before shooting that last round. The only think I can narrow it down to is the trigger disconnect that requires the slide be fully engaged before firing. I know it may look engaged. but sometimes it may not be.

Also when you have the slide off, check out the disconnect which is a flat shiny piece above the right grip. You should be able to gently slide it forward and let it snap back on its own.

While you have the slide off, put just a small drop of oil on each side to the cams on the top of the frame. Pull the trigger a few times to work the oil down to the shaft the cams sit on.

I don't recall reading it above but how are you cleaning and lubing your gun? Do you oil/grease according to the lube chart?

What is driving folks nuts is how in the world does the gun know it's the last round? Have you tried putting only two rounds in the mag? Have you had anybody else shoot it and what happened there?

This one is different enough that if you live in central CA I'd like to meet you at a range and see it, but try the stuff above first.

[Bawanna]

Yup, he said he tried with full mag and then a mag with only two rounds.

This ain't making a lick of sense to me. I wonder if the follower has a boggle and after the last round leaves it's slowing the slide down not allowing it into full battery? Then your giving it a smack idea would make it shoot.

Like you say it sure sounds like the disconnect is not allowing it to fire.

Only thing it can be.

Yup. My money is on the slide being slightly out of battery. Now, the question is, why only on the last round?

[OldLincoln]

I second what Bawanna said, that the mag is causing drag keeping the slide just out of battery. It may even be the follower doing something to cause drag on the last round with the same result. That would explain the last round and the disconnect. The slap on the back of the slide will make it clearer.

If this is it, he really needs to replace the recoil spring at a minimum. I recommend what I did which was replace all the usual springs: recoil, striker and mag springs. I went with the Wolfe stronger springs for recoil and mags and standard for striker (sorry Jocko), it came with the recoil spring..

Maybe polish the slider, too?

[Longitude Zero]

It sure sounds like an out of battery condition. The magazine can be completely out of the weapon and the striker will be reset by reciprocating the slide. The weapon does not even need the magazine in the gun to reset the striker.

[JFootin]

Well, if it is the mag, Kahr will certainly replace it. Better if you can convince them without sending the gun in. But if you have to send it, get them to send you a prepaid freight label.

[rwehnau]

Gentlemen:

It has degraded to the point where it will not even dry fire without jiggling the slide.

Return authorization has been requested and this device will be on it's first trip to repair.

Please...no more responses, my frustration level with this new gun is now at it's peak.

Thanks

[OldLincoln]

Rwehnau. Okay, sorry this one is a problem. I hope they get it fixed right and back to you soon. You have worked with us well and sometimes we tend to work problems till the cows come home. Please do let us know how it eventually works out.

+1 This is an unusual problem and we'd love to know what the cause and solution was? Kahr customer service will take good care of you. :)
