The Pedersoli .45 Cal Kentucky rifle I bought off Gunbroker last year shoots 6" low at 50 yards. This normally would be an easy adjustment EXCEPT this rifle has tiny brass sights. I am talking really tiny, like .19" above the top plane of the barrel tiny. They look more decorative than functional. So I have ordered new sights from TOTW. The new sights have slightly larger dovetails than the rifle has. My question is simple, Which do I modify? Cut the rifle to match the sights or the sights to match the rifle?

This is one of those personal choice things. Were it me, I'd modify the sights over enlarging the dovetails,,, but at the end of the day - it's your choice. :shake

Ditto what Joe said.
But on the other hand, what you have there is a standard metric dovetail. If it were me, I would enlarge the dovetails on the barrel for one reason. If you should ever want to change sights again and get a sight set the is standard 3/8" dovetail, you won't have to repeat the procedure. File it once and be done with it.
I think the metric is about .360" and the standard is .375. There is not a lot of filing to be done on the barrel.

I'd be inclined to enlarge the dovetails for the same reason Smoke gave.

.
If the sight you ordered isn't steel, I would think it would be a lot easier to file it, ILO the barrel - if it gets messed up, it's a lot easier to get another sight.

The sights I ordered ARE steel but a much softer steel than my barrel so I'm modifying the the sight first. Much lower financial pain if I screw it up! In future I can modify the barrel, if needed. Thanks for the help! :hairy

If in the future you do decide to enlarge the dovetails in the barrel, here is a thought on the file.
Get a triangular one that has a smooth side. Use the smooth side against the barrel. As a guess, I would think Brownell's might have such a thing.
Yes, I just looked it up and indeed they do have such a thing. A little pricier than I would have thought, but what else isn't?

Or, make your own with a regular 3 sided file and grind down one side. Just go slow so you don't take the temper out of the steel.
