TTN SXS Firing Pins

[John E.B. Rawton]

I have this used TTN. Last Saturday I was shooting, using brass shells and WLP primers. I had random misfires on the right hammer side. 

While I was cleaning, I found the right pin was short compared to the left so I ordered slixpins and read that I might need to trim springs. 

~ Has anyone done this?

~ Will a standard socket loosen the assembly?

You'll need a thin wall 8mm socket. You can grind a std 8mm to thinwall.

You'll probably have to remove the hammer, same 8mm, to get to the firing pin nut.

I think this one is 5/16".  I probably made it up for my Colt 1878s.

Ditto on the socket. I did not have to do anything to my springs.

Think I used a boxed in wrench to tighten my TTN hammer pin nuts.

I also use an 8MM socket that I have ground to thin the walls so as to fit in the firing pin recesses.  

 

The retaining nut is also slightly tapered on the faces, so the root of each face is slightly larger than the tip.   You may have to make a kerf cut with a fine hackblade to get a firm grasp on the nut, slicing perhaps 1/4 of the way from the opening on the socket towards the square drive end.

 

One of my TTN's recently starting hanging (sticking) the firing pin in the fired primer.  Thus preventing opening the action until I bounced the gun on the recoil plate hard.    I had to install firmer springs than the factory installed, and now have reliable operation.

 

Good luck, GJ
