The firing pin seems too short...

[dgray64]

My neighbor bought a used New England Firearms Pardner Model SB1 single shot 12 ga used at a garage sale. He bought a box of shells and they dent the primer, but don't fire.

He's a disabled vet of Viet Nam era and he wanted it for home defense as well as deer hunting from a blind since he's pretty well wheel chair bound.

Anyway, where would I find a new firing pin for this?

It looks like I could drive out some pins through the receiver to get it apart to replace the parts, but I need the part. Thanks for the info.

Thanks,

Dave

Sounds more like it needs a new hammer spring.

I'd be talking to NEF about returning the Gun for a factory service.

When a fairly recent manufacture pump shotgun malfunctions like this, it's usually a symptom of either a factory defect, or some "Billy Bob" altering something for some reason.
You could spend money and time replacing parts and still not get it fixed.
If something has been altered, the gun may be unreliable when really needed.

Since these guns are so recent an import, finding parts will be very difficult from anyone BUT NEF, and like many gun companies, they will likely be reluctant to sell critical parts unless THEY install them.

Umm..isn't that a single shot, not a pump?

It may just need a good cleaning and some lubrication. Be sure gun is unloaded, then remove forend, barrel, and buttstock. Soak receiver in mineral spirits or kerosene for 30 minutes. Remove, and allow to dry. Lubricate lightly with Breakfree CLP or Rem Oil. Reassemble and try it out.

While you have the buttstock off, push on the firing pin and see how much it protrudes from the receiver face. This should tell you if the firing pin is too short. I doubt that the gun has been fired enough to wear the firing pin enough to shorten it enough to cause it to misfire. It usually takes LOTS and LOTS of shells to cause that.
