Welcome to the forum, Brassica. That's a very nice pistol. Congrats on landing that one. Looking forward to seeing more of you around here.

.020 cylinder gap can give you issues. Recommended gap for the Colt reproductions is .002-.005. Initially you can probably live with it with the negative results being lots of flash-over and potential chain fire issues if you don't have a tight seal or insufficient lube over the balls. Long term, I'd be concerned with the cylinder having a 'slide hammer' effect on the frame and possibly battering the wedge.

I suspected something like that. Any idea what I could do to improve it?

I think the only cures for the large cylinder gap would be, removing material from the end of the arbor, and a like amount from the barrel lug. And then re-fitting the wedge. But I doubt you'd want to perform such modifications to a valuable original gun.

You could also have metal added to the forcing cone by having it TIG welded. But again, major mods to your original gun.

Other than that, I don't know how else to close that gap. Hopefully 45Dragoon will weigh in and give us his opinion. He's the true expert.

I would add some material to the the end of the barrel (TIG welding with a copper rod in the forcing cone, to make sure not to get any bumps inside), then with a guiding rod in the barrel, grind the welding down, so the addition is about .4  millimeter.

A temporary, non-altering approach would be to turn out a sleeve to fit over the outside of the forcing cone and glued to it. Material thickness .3 to .4 mm
