I know this is a revived thread from last year (seriously, why is everyone dragging up old threads all of a sudden?), but I just visited Guns Galore today, so thought I'd weigh in.
It's a small store, but literally jammed to the rafters with guns. They actually have those library-style sliding ladders to reach the high stuff.
They had some okayish prices on some used stuff, but not amazing. And plenty of higher prices, like $375 for a Yugo SKS. I know prices are up, but still...
Even though every gunshop I've been to in 3 months has been full of Obama talk, it was more vitriolic than I'd heard yet. Plus a clerk was telling a Ft Hood soldier the old racist chestnut "Yeah, Obama complained to Fox News that they needed to double the number of minorities they show on their programming... so now they're showing Americas Most Wanted twice a day!"
They weren't necessarily unfriendly, but not horribly helpful either.
If you're in Killeen, the two pawnshops immediately south of 190 (Action Pawn and the one just a block south of it) have a buch of guns, and a few deals mixed in. I also got a somewhat rough Benchmade 9100 auto (labeled "MILITARY AND POLICE ONLY) for $35 from one pawnshop, so I'm happy.
