I have a Stinger (commander slide/officers frame).

I have two problems with the gun.

First, occasionally I get a reverse case jam. That is, the case, after firing, is stuck between the top of the slide and the barrel with the open case mouth facing rearward. Maybe once every 50 rounds. isn't related to the number of shells in the magazine.

Second, I have fairly high primer strikes. The bottom of the strike is on the centerline of the primer. The strike is .025" higher than it should be. The gun has a Kart easy fit barrel with the raised pads in the rear top barrel/slide locking lug. I checked and I have about .040-.045" rear top lug engagement. It appears that no work was done on the pads to raise the barrel into the lug. Thats what I think causes the high primer strike, and maybe my ejection problem as well. The extractor is a long one. Case examination reveals a good grab on the case, and there is a nice ejector mark as well. Nothing bad looking there. Extractor appears to adjusted ok also.

Since refitting this barrel is out of the question now, I'm thinking of installing a new Schuman barrel.

Would this cure my ejection problem? FYI, I am not the only one with this peculiar ejection problem with a stinger. I found 3 people with the same problem on the other board. This doesn't sound like a fluke problem to me.

Anyone ever have to deal with this kind of problem before?

I don't have any intention of returning the gun, I want to fix it myself. I like the gun, but I have to solve this problem.

Hi Peter...sorry to hear of your woes...

Could you tell me why it's too late to re-fit the barrel? I'm not up to snuff on this and just want to learn a trick or two related to barrels and fitting. It does seem to be one of the "darker" arts in pistolsmithing

 

[Peter Zahn]

gyp-c2,

Bottom lugs are already cut. Seating the barrel deeper into the slide would raise the bottom barrel lugs and they won't make contact with the pin anymore. At least thats my reasoning. I could be full of it too.

 

[gyp_c2]

What about the round following the jam? Does it feed into the barrel or what?

 

[Peter Zahn]

The slide starts to chamber it, but when the the gun jams it stops. Nothing wrong with feeding.

I'll probably start off easy and replace the recoil spring with a heavier one to see if I can get the jamming to stop. maybe try a different ejector profile too. Then I'll address the primer strike issue.

Here's the link to the discussion at 1911 forum for those of you who are interested.

My stinger does the same thing.

Jim,

I have been doing a bit more checking on this problem. In particular I have examined a fired case to find the ejector and extractor marks.

Like I said before I have high primer strikes, which would indicate that my barrel sits a bit too low in the slide.

I noticed that this would substantially change where, in relation to the centerline of the case, the extractor and ejector contact. I'm beginning to wonder now if occasionally the case doesn't clear the slide cutout on the right side. It might hit the inner slide wall and get spun around from remaining ejector eneregy as it pivots around the extractor. The ejector seems to be hitting high enough from center to allow this.

I have a hard time resolving myself to the assumption that this gun doesn't like low weight high velocity rounds. It is in fact just a commander in its operation and I have shot enough of them to know they eat this ammo pretty well.

I'm considering getting a new ejector to try and stone it down a bit to lower the point it contacts the case, and maybe raise the angle the case flies out at a bit. Some slight extractor work might also be necessary.

What do you think?

Peter,
Just my thought here but if the primers are getting hit center I would first address that problem. There is soem pretty basic stuff about a 1911 and they will work in an amazing set of circumstances and conditions. But seems the primer hit and barrel fit in these guns could have been done better. I would start there. The cycle time of the light fast bullets is making things worse. But you know the basics. Reverse engineer the thing and start at what you know is wrong and fix it first.

I'll be back next week, if I can help, just give me a call in the shop and we can jaw jack it into submission.

 

[Peter Zahn]

Thank you for the info Dane. I may take you up on the chat offer.

Seems that I should have somehow checked for the high primer strikes before I bought the gun. My bad.

But, it will be an interesting project.

Hey Peter...Have you read any of those barrel fitting threads or articles from Brownells?
I seem to recall one that was pretty detailed and might help some...I'll look for it...

http://www.brownells.com/benchtalk/03su ... /index.asp


There are some others there as well...
I have a couple other links that have info, but it's pretty basic and I'm sure you've already considered this stuff...Just for grins, here they are...

Good luck...
:wink:

 

[Peter Zahn]

Thanks gyp-c2 Ill check them out too.

 

[Peter Zahn]

Well damn Gyp-c2 I did learn something new. Now I know why I have what is called a skid mark on my primers from the firing pin. Well I suspected why but it's nice to get a confirmation since I've never seen it before.

 

[gyp_c2]

Cool!
...When you get to Wilsons' diagram of the extractor, and refer back to the tech section re: the ejector...There may be something helpful there as well...Good refresher...'specially if you don't have a proper"example" around...

Was the section from Brownells' helpful at all?
Thought maybe the steps to properly fit the barrel might give you a picture of something to look for while troubleshooting your pistol...Oh well...Let us know if you discover something...

:wink:

 

[Dane Burns]

Peter, darn hard to check easily when you are buying a gun. It can be done of course. But I have to admit I have never even though of looking while shopping for new or used. I just assume that the gun is right internally. On a custom gun from a reputable maker I would follow through on a warrenty issue if it were put together incorrectly.

Great references posted gyp, thanks!

 

[Peter Zahn]

Dane,

I think you have a point about the warranty thing. The gun is less than a year old. Anything I can think of to make it right could cost a pretty penny. I just sent an e-mail off to les baer. We will have some first hand up to date info on thier warranty and attention to customer satisfaction after this. I will make it a point to inform all here as to what exactly transpires.

 

[JiminCA]

Hey Peter, sorry to take so long to respond to your inquiry above.

I have called Baer on this and they asked me to send the gun in. I have owned it for a couple of years now, and I got the impression that they intended to fix it regardless of how long I've owned it.

I have avoided sending it in as it is my CCW piece and here in CA CCW guns are on the permit by SN and I don't have another 1911 on my permit.

But I will send it in over the next few weeks. If they can't make it right I'll send it to another smith.

I think you're on to something with the off center pin strikes. Mine strikes high too. Maybe a newly fitted barrel is part of the answer.

Jim

[Peter Zahn]

Jim,

I got an immediate response from Les Baer first thing this morning from my weekend e-mail. He also wants me to send mine in, which I think I will, probably tomorrow. It's my carry gun too, but I can carry anything I want in my safe.

I really want to give him every opportunity to correct this problem, and hope to have some good things to say about his warranty work. They sent me a nicely worded e-mail expressing thier concern over my problem.

I'll be sure to keep everyone posted.

 

[Sam]

Peter, So what happened? Sam

 

[Peter Zahn]

sam,

I'm still waiting to get my gun back. 12 days ago I called them, and they said it would be done this last week. That would have made 3 weeks. We're into the fourth week now.

I haven't forgotten, just waiting for something positive to tell you all. Oh yea, I'm not afraid to post the not so positive if need be.

Hope to have the results next week.

 

[gyp_c2]

...still no word?

...grrr
:wink:
