You lucky dog! If you decide it aint quite what you want it will go fast here.
If you like rear peeps that would do well, though you will need a taller front sight (someone will chime in on what works, and/or check the FAQs) and be a 'handi' configuration.
As for the hammer spur blocking the view, by then the shot is long gone. I shoot with both eyes open so I get a view anyway, but if you are a 'one eyed jack' you wont.
