I guess if one doesn't understand front sight picture, he or she wouldn't appreciate a more prevalent front sight.
Yes, I'm aware that "pocket pistols" are supposed to be used "close in." Well, if I'm that close in, I'll stick to a Seecamp; but the Rohrbaugh has enough range to warrant a good front sight. Just think of it as an added bonus should you have to use your R9 to stop some thug from doing the unthinkable, some crazy more than 3 or 5 yards from you getting ready to mow down a whole group of people. That front sight picture may just help you accomplish that, the easier it is to see, the better.
Don't believe in front sight picture...go take some training classes. That's all I'm going to say.
