I've noticed that the firing pin does not protrude very far at all from the rear of the breech (where the hammer contacts it). When I push it flush with the breech with my finger and slowly release it, it is BARELY above being flush with the breech. If I tilt the gun backwards and tap (or pull it out with my finger), the full length of the firing pin is exposed, much more so than when it is depressed and slowly released. Basically what I am trying to say is that the spring provides very little resistance in forcing the firing pin to be exposed to the rear of the breech; very little is above flush (it almost looks flush) unless pulled out by hand or gravity (but of course, there is nothing to keep it at that point). I disassembled the firing pin assembly and cleaned it, but it didn't change anything. The spring seems to short.

Is your firing pin the same way?

What normally happens is carbon will build up either on the under side if the fireing pin or in the cup it self that does not allow the pin to fully extend out of the cup.



Look at the picture of the firing pin near #3... carbon can collect on the < (angled) surface of the pin and in the cup where the angled surface contacts the cup in the firing pin hole. This can also cause the pin to be sticky - not want to return.

I can't see the pics (some are blocked at work) but my pin is not sticky. When I pull it out to its full length (or it just falls all the way out because I'm tilting the rifle back [muzzle up]), there is no spring resistance when I go to push it back towards the breech; it basically free floats between being fully protruded and just shy of being flush with the breech. I disassembled the firing pin assembly last night to make sure that it was clean. It was, but I cleaned it anyway just to be sure. All channels are clear, no carbon build up, etc.

I basically feel like the spring isn't long enough for the firing pin. It was a tiny, weak little thing.

could make a new spring for it. The clicker style pens have a long spring inside

You are correct it is a very small weak spring.... this again is going to sound dumb but the spring must be in the assembly in the correct direction or it will not return the pin.

Another thought you could/can pull the spring (carefully) to extend its length - but it still has to go in the assembly the correct direction. If I remember right it is a cone shaped spring??? When you can see the drawing/picture - you will see the correct orientation of the spring...

Yeah that's what I was thinking...was just trying to figure out where to get the correct size spring. The Omega's spring is actually tapered.

You are correct, it is cone-shaped. I tried it both ways just to make sure I didn't reinstall it backwards.

I stretched the spring out and emailed T/C to ask that they send me a new one. For backup purposes. Problem solved for now! Thanks all.

Discovered that the issue was moot to begin with. Even if the spring is not pushing the firing pin all the way back towards the hammer, once you have a primer in there, the primer will do it. On the breech side, the pin does not recess any farther than flush with the breech. So, even if it is poking through the breech a bit (i.e. the spring is not holding it back), the primer will ensure it's sitting flush and that there is plenty of pin for the hammer to smash.

To see if the fire pin is not seized ,put one finger on the fire pin pull the hammer and squezze the trigger ,you shoud feel the firepin sticking out on your finger.
