I had a problem with my 12 gauge O/U today at the range, and am looking for advice on whether I can repair it on my own.

One of the firing pins came out about 1/4 inch after the being fired, and the gun wouldn't close as a result of this. The pin seems broken to me, but I am not sure exactly how the mechanics of the pins work. The gun is a cheap Yildiz, and has had about 3000 rounds through it over the last 3 years.

I have never taken a O/U receiver apart, should I attempt it with minimal gunsmithing experience? I know my local gunsmith will have to order the parts from the same guy I will, so I thought I could bypass the gunsmith and do the labour myself.

Any advice?
 
I have a similar problem, but slightly different. The firing pin stays in the struck primer after firing and becomes a real problem opening the break action to eject the shell. I believe it is a weak stretched spring that is supposed to retract the firing pin back into the breech. The cause is from excessive recoil (again I believe) from me simultaneously pulling double triggers with 3" magnums loaded. Both my double shotguns have this problem now. :redface:
Maybe your problem might be caused from this?
 
You can always try fixing it yourself. If it doesn't go right, you can always take it in a garbage bag to the gunsmith, something I'm sure he has seen often.
Does the Yildiz have bushings on the face of the breech? You may see what looks like a flat disc with either 2 or 3 holes for a bushing driver. If not, the firing pin comes out from inside the receiver, requiring the buttstock to be taken off and a few other things removed to get at the firing pin.
I say you can do it, but only you know what your mechanical comfort zone is.
 
Here is the view of the breech face. When I remove the phillips screw shown nothing happens, but I haven't tried to really force anything yet.

I haven't seen this setup before...
Try taking the screw out and lightly tap the oval with either a soft mallet or a dowel. I'm guessing that the plate is a close fit and is held in by friction fit as well as the screw. Careful when and if the plate starts to come out, the firing pins may come out due to a rebound spring. If and when you are able to get the plate off, you should be able to inspect the firing pins and the springs. Check that plates face as well, the top firing pin hole seems like it's pushed out from the firing pin.
 
Disassembling and then reassembling an o/u can be tricky work. Maybe you should see your local gunsmith. If you do disassemble and take the parts to a smith in a green bag, it's known in the trade as a "bag gun"
 
If you do take the screw out, the plate is probably spring loaded, by the coil springs that retract the pins, be careful or you'll lose the good one and have the broken one. You will still have the problem of finding the spring match.
 
I'd take the rear stock off too and have a look from the other side before trying to take off that plate. Use a digital camera and take photos of the work as you go along.

Schematics would be usefull.
 
Well I got impatient and stripped the Yildiz O/U down. I removed the stock, which made diagnosis of the problem pretty easy.....broken lower firing pin.

Now the problem will be finding someone who sells firing pins for the Yildiz here in Canada. If anyone knows of a supplier of these pins please let me know. I hope I don't have to wait for one to come all the way from Turkey.:mad:
 
After no response from the Yildiz dealer here in Alberta, and no help from anyone in the U.S.A., I was forced to get a couple firing pins machined locally. The cost was resonable, and it beats waiting for the brutal customer service from Wide North. I wouldn't recomend using them again.
