If the rib is attached with screws, bend away. If not, install some countersunk screws at intervals then bend away. It probably won’t take much bending/flexing to fix the problem.
If that doesn’t work you still have the option of cutting the barrel. But The barrel shortening may only lessen the problem, not eliminate it.
A poster asked for muzzle pics, will do this evening.
A pro will do the work, don’t worry.
Shortening may not fix the problem. I have a new rear sight that I was going to cut the notch way over to the left, and I know that will resolve it…but I just don’t like the looks of that.
The improvement of handling is one of the driving factors here, and the originals were shortened due to barrel splitting at the end. I think it would make a great saddle gun, and be more useful to me than a poor handling wall hanger…
Appreciate everyone’s input.
