Not sure about Austin but there is a Cabelas down the road in Buda. They had a few good guns in there a week or so ago but extremely over priced. They also had an 1894 "trapper carbine" and an 1892"short rifle for $4450 each, unfortunately both have had their barrels cut to the shorter length–and none too interested in entertaining the possibility they are not original. Not sure I would waste my time with them.

A quick search found:
