I would bet a lot that the pin is not the problem. It may be the bolt like Fusil mentioned or something else.
Also, I believe English shotguns were traditionally made to have the toplever center when the gun was closed (this isn't the case with all of them today). I think they did this with the way the bolt/spindle worked with each other.
If your 'smith doesn't know this stuff, get your gun away from him ASAP. All he'll do is mess it up and make more work for another gunsmith down the road.
And if the gun needs a new pin, put in a new 'friggin pin. You're talking about a Boss, not some Spanish thing or something like that. Fix it the right way. Best guns deserves to be treated in the best manner possible. Don't abuse your's with short cuts and second rate repairs.
