Maybe all those guns were made in an alternative universe.

Pretty sure that if I had some way to travel out of this particular hellhole I wouldn't have bothered to return. And if the guns are floating in I'd be looking for that entry point.

Maybe the confusion Wonko is due to most posts being about SXS and the shotguns you refer to are OU.

As for Beretta action shoulder fitting, I heard from a Beretta fitter at the factory that the shoulder must have a relief of one tenth of a millimeter, about four thou, and that is also included in the instructions to service gunsmiths who go to the factory for training in repairs.

In an alternative universe .004" will not allow daylight to pass through.

I have read all the posts about clearances and lack thereof. About 40 years ago, I fitted a set of barrels to my K-32 Krieghoff. There was a gap at the breech face as big as a fried chicken wing. I asked the chief gunsmith at Krieghoff USA, Ottsville if he could replace the trunnion with a bigger size. His statement was similar to "It's a shotgun, don't worry about it." End of story is that this has been my main competition gun for that 40 years and has been problem free. Obviously, the fit of the forend lug has drawn the barrels into the trunnions and made everything work without a close fit at the breech face. How does this fit in with previous posts on this thread?

Gee ,,eightbore and the primers stay in ? What about headspace I have a k32 I think I'll check it out today also my Beretta that wonko say can be off face by design and function.i will report what I find.

Yes, the primers stay in, in all four gauges. I don't take any pains to install the small gauge tubes out a bit, so they meet the breech face. In fact, I have never thought to do that. I don't expect your gun to have excess headspace like mine because you probably have the original barrels. In a previous life, back to 1967, my gun was an ATA trap gun and I traded the trap barrels for my tubed skeet barrels years ago. For your information, all the Beretta barrels that I have fitted are tight to the breech face. As a side note, Wonko describes the replaceable gizmo at the rear of the monobloc as a wear item. Only the high end Berettas have that feature, 680 series guns less than 682 don't even have them. I have hundreds of thousands of rounds through a 682, have replaced locking pins after the lever went to the left, but have never replaced one of those "gizmos" nor do I know of anyone else who has. They are absolutely not necessary in keeping the gun tight. I have read that they pull the barrels away from the trunnions, for whatever reason I don't know.

My 32 and 686 both have trunions I blacked the action face on both put the barrels on with the forend opened and closed the guns viola both barrels have pressure on the trunion and breach face a clear outline in the smoke reside so they are on face, both guns have a metal piece machined on the barrels that contact the top of the actions the Beretta has locking pins the k32 a sliding hood .what I have learned is on these model guns the barrels rotate on trunions that hold the breech face to the action and metal machined on the barrels keep the barrels on the top of the action tight when the locking device is engaged.so they are on face in a traditional way but don't seem to have the gap required on a sxs.the end
