These are my favorite of all the cap-n-ball pistols. The 1858 Remington is mine and the 1860 Colt I gave my son for Christmas.
I have done a tune up on the Remington, polished all the moving parts, lightened and shortened the trigger pull, and it is a sweet shooter. The groups are nice and tight. The point of impact is center and low. That's an easy fix to file the front sight down and raise the poi.
The Colt is pretty smooth. The trigger has quite a bit of creep, but I can fix that. It is shooting good groups but the point of impact is about 18 inches high. Where can I get a taller front sight? Or do any of you have an easier fix for that? I don't think I want to adjust the rear sight / hammer.
