Is there are firearm that does not fit one of these?
You missed the "match lock",Flint lock, Cap lock, and "hand cannon" and yes they were all developed for military use, though I don't think even 3rd world countries are using them any more there are probably still some in the far back corner of an armory somewhere.
I didn't realize there was another page when I first posted this, but to answer TAB. just because they are not CURRENTLY classed as firearms means nothing. The only difference is that they do not use pre assembled ammunition. over look that detail and a Springfield rifled musket becomes an "assault weapon", a "military rifle" that , as the messiah said, has no place in our society.
Anti's suck.
