McBride's, Red's, Heritage, Cutting Edge Armorment(?) in Round Rock, Cabelas in Buda. Those are the ones I know about that handle KelTec. I have not seen them at Sportsmen's Warehouse but I may have missed them.
I was at the gunshow yesterday and saw a bunch of them, if you can wait another month. You might save $20-$40 or so by doing that maybe. Not sure.
