Have you called Sportsman's Warehouse in Round Rock?
McBride's on Lamar will probably have one. Their website says that they carry them.
I actually emailed them and they said they didn't have any right now. I was pleased with how quickly they responded though.
A lot of people give them grief because they are sometimes a little overpriced. Joe runs a tight ship there though, and he will fix people's problems. They are an authorized repair center for many brands and they will get it where it needs to go if they can't deal with it. I've been shopping there for years and have nothing but good things to say about them.
They also have a reloading area and the guy who runs it is a wealth of knowledge, he has given me a novel's worth of helpful information.
