Fitting A Squires Bingham Model 20 Firing Pin.
Hello!
I'm looking for some guidance/info on how to fit the above mentioned firing pin. When I install the firing pin, it is too short to contact a cartridge casing. Also, the bolt won't go all the way seated with the firing pin installed. If I remove the firing pin, then the bolt will go all the way forward. Do you think this is a fitting problem, or do you think that I have the wrong firing pin? Does anyone have the exact overall length of this original firing pin?
Thanks for any info you can provide, and stay safe!

Couple of years back, I was working on a Tanfoglio 22 conversion unit, with the same problem. Only in reverse, it was to short. Your either going to have to get another firing pin, to see if it will fit? Or more likely they are all made oversize. And you or a gunsmith, is going to have to fit the oversized firing pin. This is done by trial and error. Just removing a small amount of material at a time. Till it works.

if I remember correctly I believe there was a trick to reassembly that had to do with sear
I actually have one all apart at this time that I am restoring so when I get a chance I will put the reciever back together to bring it back to my mind

I believe that I have the wrong firing pin. There is no way that this firing pin can move forward because it contacts solid metal before it can move far enough. The bolt was already in the rifle when I received it, so I think that part is okay. I have posted some pictures to show the firing pin in the bolt.
Thank you!

I have been working on these older revolvers, rifles, and shotguns for most of my 76 years on this good earth. I have never taken my problems to a gunsmith, and guess what; I still have all of my fingers, both eyes, and have never hurt myself or anyone else by repairing and restoring my firearms myself. I appreciate the information and help from this and other gun-related websites, and I use the information I can gather to help me to stay independent.
Thank you all very much for your knowledge and willing to help!
Stay Safe!
