I'm headed to Austin Texas on Wednesday, and be there for a week. I want to go to a gun store(s) that caters to cowboy action. I live in California, so I don't know what gun stores are available in the Austin Texas area.. Thanks for any information. BGB

I have an Uberti 1873 357/38, 20 " barrel. Is the magazine tube insert worth purchasing? Aluminum or carbon fiber? Does anyone have the specs for the tube, diameter, thickness, etc. I have a McMaster Carr supply about 2 miles from me..... Thanks Bloody Glen Bob
