| I inherited a NEF single shot 12 gauge shotgun. When you go to shoot it the firing pin is not hitting the primer with enough force to fire the round. Any ideas whats causing this and would it be worth getting fixed? |

First, measure the firing pin protrusion. It's probably okay, but won't hurt to check. Look for about 0.060 inches.
Next, take the butt stock off and spray the guts of the action with solvent in case it's gummed up with oil and dirt. Or WD-40 and dirt. Do that anyway, then relube the innards with light gun oil. While it's apart, try to determine whether the firing pin is broken inside the receiver. Finally, eyeball the main spring. I looked at parts for a Pardner shotgun on Numrich, I see a mouse trap spring on the hammer. Don't know if yours is the same assembly, but that is a good suspect to check. Cost is less than $3. http://www.gunpartscorp.com/catalog/Products.aspx?catid=3626 Hold your breath a second, drive that hammer pin out, and change the spring yourself. Use a good punch. |

I agree with all this stuff but start with the easy stuff, clean the daylights out of it. These were guns dragged around in the woods and tossed behind the seats of trucks and good chance it is just gummed up and full of crud . Not worth paying somebody to fix it but the whole gun is a spring and a fireing pin , sounds like parts are available and cheap so have at it |

The butt stock has to come off to clean the action. Even if the whole assembly is just dropped into a bucket of solvent.
The hardest part of that task is using care that the screwdriver doesn't get wedged between the screw head and stock way up in the recess, causing the stock to split when the screwdriver gets a honkin' big torque. |
