Strange problem with Dan Wesson 9mm

[drband]

It will be a simple fix.

I'd start by putting a drop of oil on the disconnector tip, letting it seep along the sides, to see of that works. It might be as simple as that since more rounds might burnish the tip as needed.

I like to try the simple stuff first.

On every new gun I get, I spend the first 3 or 4 nights with the gun hand racking the slide and dry firing (not rimfires) somewhere around 800 to 1000 times. This gets the surfaces mated together and smoothed up before ever shooting the gun with ammo. I would highly recommend doing this with the PM-9.

I just heard back regarding the outcome of sending the gun back to DW:

"The gun was sent back to CZ. They found that the person who worked on it before had put in a new sear spring … called a “split sear”. The sear spring has 3 legs and one of the legs is resting on the disconnect.

CZ will charge $6 for a new factory sear spring plus $40 for shipping, and do the following:

• Install the new spring
• Modify the trigger pull to 2 ½ - 3 pounds
• Inspect the ejector to see why it is so hard to get out
• Tune the entire gun

"

If I find out what they did to the ejector, I'll post that as well.

Thanks for the update. Odd that the sear spring was jot seated correctly if the mainspring or internals hadn't been removed.

 

[mikemyers]

I barely understand it, but after reading a description of what a "split sear" is and does, the following write-up makes it sound like an improvement, not a problem:

I don't expect to learn anything more, as my relative is just going to be happy to get the gun back, and not concern himself too much with all the details. I guess DW just saw a non-standard part, and (correctly) put in the standard part, so the gun would be "stock".

I should send my DW Valor off to get all this work done for this price!

Nice that it's a cheap and easy fix. I'm shocked that their sending it out with a trigger that light.

 

[LiveLife]

So malfunction of the pistol was due to improper assembly at the factory?

Why wasn't this covered under the warranty?

 

[mikemyers]

It pretty much was covered. Had someone not installed aftermarket parts in the gun, it would have been. Warranties are often void if you have someone other than an authorized repair center do any work on a gun, especially if you replace parts with something incorrect for that gun, or make other modifications.

That gun is a dedicated target gun so trigger weight is important. I'm sure it would be different if the gun was designed with defense in mind.

mikemyers, got it.

I tried to buy a PM7 for a long time and eventually "settled" on a railed Sig 1911 when I couldn't find one (only about 250 made for CA each year).

In my hands, PM7 feels nicer but the darn Sig 1911 keeps producing sub 2" shot groups at 25 yards even after almost 10K rounds. I am still contemplating getting a PM7 but wife keeps telling me, "Will it shoot any better than the Sig?"

Maybe I can talk her into getting one for my retirement present but Les Bauer is not much more money and 10 models are approved for CA ...

Try heavy lube.

No idea why 1911 newbs are scared of real lube. Try something thicker, it's a tight SS 1911. I don't see a drop of lube in your pic.

Has he tried manually cycling the slide on the frame with the barrel bushing and recoil spring removed to see if he can feel any unwarranted resistance? Any unusual wear on the barrel bushing around the recoil spring guide rod?

+!==also check to see if the feed ramp si clean and shiny--if not polish it--otherwise Glenn @ Dan WEsson is THE MAN

my brand new specialist locked up after firing roun d #8--Glen made it right--it operates so smoothly these day--no mor e issues-- CZ and DW offer top notch service

 

[dwhite]

I almost gave up on my Stoeger Cougar after having a similar problem.

Finally figured out the thumb of my right hand was riding the slide when using a two
hand grip. Did not take a lot of pressure to cause the malfunction either. Figured
it out after shooting it one-handed.

Grip is a possibility.

All the Best,
D. White

(I'm not sure how to mark this thread as "closed" or "answered", as he now has the gun back from DW and says it's working fine. I posted what they found up above, and probably I'll never know everything they did...)

 

[robertg5322]

Is he left handed?

I had the same issue and have seen several left handed shooters at USPSA matches experience the same issue with ever 1911 I shot until I started grinding the slide stop pin flush with the frame.

Left handed shooter's thumbs tend to migrate to that spot and in recoil apply pressure pushing the slide stop out. Racking at that point usually clears the issue until next time.

It's weird, cause I and most of the left handed shooters I see with this issue don't think our thumbs are anywhere near this pin protrusion, but in recoil, it goes there.

Ignore this if the gun already has a flush slide stop pin.

Something similar happened to my Pointman 9 on my first range trip . I called CZ and they told me to send it back . It didn't cost me anything and I had it back in about 2 weeks . It works fine now .

 

[robertg5322]

What did they say was the issue?
