Old 1917s and the like are fairly easy to shorten and reset a new front sight.
Worst part about it is that the lettering on the barrel usually ends up getting cut so the work is apparent to anybody who handles the revolver.
I agree with both sides on this issue IF your revolver is a 1917.
About 20 years ago some 10,000 1917 revolver replacement barrels came into the country from South America and Israel.
They are not too hard to find if you do some looking, they have no markings on them and and they aren't all that expensive, should be around $100.00 tops.
Buy one of these barrels, have it cut down and fit to your revolver and keep the original barrel, "just in case" you ever wish to return the revolver to its original state.
Total cost for the operation should be less than $300.00 including the new barrel.
