I've bought a few rifles and pistols from CDNN, nice prices, no problems. Don't have any idea if there's a brick & mortar store you could visit in Texas. Nothing would surprise me. If you go to Texas for gun shopping, here's where I used to shop. I'd go in and 'wish' in here on the weekends, it was a few miles from my apt:
Grabbed a pretty sweet old shotgun recently. Had a model 11 Remington stolen from me back in '74, have always been watching for another good one to take it's place. These are the old Browning A5, sold with another label, for my purposes. John Browning (PBUH) churned out some of the finest guns, ever, and I've always shot well with this type of gun. Not fast, mind you, but well.
I found one of the model 11's, with some of the prettiest walnut I've seen. Made in 1928 - she needs a repair to the safety for my peace of mind but is in fine shape otherwise. Anyway, getting the old girl makes ME happy. You kids and your kooky music!
