I'm recently back into 1851 Navies after a 15 year hiatus. My new Pietta revolver shoots where they all have, about 8 inches high at 15 yards. Nice groups though.
In years past I'd file down the hammer notch.
Doesn't seem like the right thing to do now.
Are there replacement front sights that are taller? What do all the CAS shooters do? Do the front sights on a Pietta screw out?
