Firing pin drawings

Posted by John Mistretta on September 22, 2023, 6:07 pm

My nephew and I were talking about L C Smith shotguns. He has a lathe and milling machine among other tools and teaches the use of these to students. He got rather excited about turning some post 1913 firing pins for me. I sent a 12 and a 20 gauge pin to him. He generated these drawings from those pins. Both of these were out of guns I currently use so I realize these dimensions may be peculiar to my guns. However they can be a good jumping off point for anyone interested in turning out some firing pins for their own guns. Either by themselves or by a machinist. Please feel free to use or share.

John, that is very nice of your nephew to make drawings of the firing pins. The only thing I can add is that in Brohpy's book "Plans and Specifications of the L.C. Smith Shotguns" there are no drawings for individual gauges meaning that the firing pins for a .410 to 12 gauge Featherweight guns are the same. For the Regular frame guns there is a slight difference in the overall thickness as shown in your one drawing.

To see the dimensions, hold control and hit the + key until you can see it clearly. Don't forget to hold the control key and - key to go back to the original size

Thanks Dave. I’ve read that before that they are all the same size. I’ve always been confused because my 12 gauge pins out of regular framed guns won’t begin to go into a Feather Weight 20. Much to wide in the collars. In my case this is what exists. Do you think it’s that all FW pins are universal? I’d love to know the answer. I really appreciatev your response. When I get the pins back I’ll post a pic of them side by side. The difference in size is obvious.

John the drawings that I posted are for Featherweight guns. On the top of the page for Part No. one is 67a-FW and the bottom is 67-FW. What the "a" means I don't know, but one is longer and so is the one in your nephew's drawing. For the Regular frame guns Part No. would be 67-R. It shows their largest diameter at .308 compared to the FW at .274-277. Basically, the other dimensions are the same except that the length of one is shorter at .907 compared to .928.
