I'm having issues with a model 37 steelbilt 12 gauge from the early 1900s.
I cleaned up the action and got the parts smooth, but it has a 10% reliability with 12 gauge shells.
If I use a sub caliber insert (.410,9mm,45,20 gauge) it fires reliably 100% of the time.
Should I order a new firing pin, or should I just replace the hammer spring.

You should be able to tell if the firing pin needs replacement by observing how far it sticks out from the breechface, or if the point is damaged at all.
Theres a pube in your grease, duhh
Yeah push the hammer forward with the action open, you should get like half centimeter. If you see that much you need a new spring, not surprising if the one in there is stock.
Yeah poor travel length.
I'll buy a new assembly.
Ty.
Definitely a new assembly is required.
Looks like they come pre-assembled with pin and spring
This is maximum.
Definitely need a new pin.
Ty guys
I agree, looks a little short.
If you're going to replace the pin I'd go ahead and replace the hammer spring while you're in there. If they come as a set that's perfect. Due to the age of the gun it's likely that the hammer spring may also be weak, so it makes sense to replace it too.
Maybe fully clean it then try again? I mean get that firing pin out and get all the rust off every surface.
God damn looks like you could use a brass bristle brush to clean that up some more.
