Emerson's minis are not always so "mini" when compared to other brands. The mini-15, mini-Commander, and others still have blades that exceed the "magic" 3 inch line. Emerson does make a couple, or did anyway, that have blades <3 inches. The CQC-14, the micro-Commander, and the Traveler (disco'd) are the sub-3" offerings. Travelers are still available from some dealers, but the model is discontinued.
On the Snubby, Emerson has dropped a sub-3" blade into a full-sized handle to make a knife for folks with larger hands that will still be legal. The Traveler and micro-Commander have a handle more appropriate to the length of the blade. I don't remember whether the micro-Commander has been disco'd or not, but they are also still available from some Emerson dealers.
Like gooey said... bolstered Emersons are either custom made from the shop, or they are aftermarket customs sometimes called Po' boys. Some of these are quite nice and very high quality work.
