Have a Meriden Firearms hammer gun, I believe M-97 of about 1914 vintage per the Meriden Arms website ( a great resource by the way). Question-- is it supposed to have return springs on the firing pins? The pins stick pretty far -- enough to prevent complete opening of the gun when they are extended. So you would think it should have springs. However, the gunsmith says there were no springs on the pins when he opened it up. Maybe not a big deal when you have shells in the gun? Thanks for any thoughts or experience.
