Firing pin seems to stick.

[B. Dudley]

Just looking for some ideas or maybe others who have had the same issue.

I have a PH grade 12g. that I have been shooting skeet with occationally for a year or so. It always worked great but recently it has been hard to open after firing the gun. I have to bump it on my knee to get it to open.

I have narrowed it down to it only being the right barrel being fired that causes this. If I only fire the left, it is fine.

It almost looks as if the pin is sticking in the primer as I can see just the slightest sign of a drag on the primer after getting it open.

I was using Federal ammo. Maybe the ammo was the issue? But I would think that both barrels would be giving me trouble if that were the case.
