I look to the form and function, style and design, and use the originals as a guide line our ancestors traditonaly used a variety of different styles guns that loaded from the front before the cartridge era began, these used the type of sights and projectiles that were available at the time, so would a "traditional"gun today (replica, not having to br EXACT replica or .....CLOSE fasimile...) many of todays production guns or once traditional styled guns altered after market with modern sigths and shooting modern bullets do not qualify as traditional...nothing wrong with them they just do not fit in the scheme of the traditional mold..... I supect that when one defines traditional with a strong tie to history and a desire to drift toward PC then the interest level will drop considerably, as the majority of a shooters fit in the "semi" traditional category.
