Warning the following instructable deals with firearms and because of that can be dangerous. If you make your own firing pin be sure your measurements are correct if your pin is too long you could pierce the primer releasing hot gases towards your face.
This is the firing pin for a Steven M94 12g shotgun which is a newer version of my Riverside Arms 12g. And the model i was recommended for parts. This pin is too short for my gun. Hmmm What should I do? First thing i did was start calling all the mom and pops gun shops in town. The closest to a solution i received was they could make me one. Only problem with that was they would probably put quite a surcharge on a custom made part. I paid $40 for the gun so wasn't looking to spend 50% of the value of the gun for a firing pin. But i really wanted to get it firing, so i set it in my mind that I would make one. Time to study up..tick.....tock....After many hours of watching and reading i think i am ready to get started.
Equipment i used in this Instructable:
Steel rod from a printer
Dremel w/ cutting wheel
vise w/ leather to prevent gouging steel rod
Step 1: Measuring, Marking, and Turning
First step is to locate a tool grade steel rod that meets your size requirements an old drill bit will work and some can be found in printers and copiers. If you have a broken pin or know the dimensions required mark the area to be removed and make guide marks for length and set pin channel. Next take the rod to the bench grinder and as evenly as possible slowly turn the rod as you grind away material. Stop and check progress often you can take more off, you can't put it back. Once you start getting close switch to the fine wheel or finish by hand.
