I sure am glad you posted this. I need to try this on one of my pistols and this will keep me out of the gunsmiths shop. Please do let us know how it works out. I've only seen one Colt that had a front sight on it that looked tall enoth to work. Far as I know it probable shoots to the left or right. The gun was a Uberti Colt 1851 London model. I looked at it in a gun shop the other day. I don't know why they haft to put those little pimple size sights on them in the first place.
Thinks for the info pghrich.
