Webers sold me some tritium sights a couple months ago and I have bought a couple XD .45 mags from them. No worries, nice guys to work with and they will take the time to show you and gun in the shop - without trying to sell you the most expensive Kimber. Everyone has their opinions - it makes us special I guess - and the younger salesmen will give you opinions about not carrying Kel-Tecs but buying Kahrs....but they are good about it.
Ammo prices are average but I would rather order mine or go to GT or another big-box store to buy cheaper.
Weapons prices are on average if you are a sheepdog (non LE or military guy). Cheaper than Killeen area gun stores but a bit more expensive on some guns than Austin gun stores. Again, I shopped for XDs and Glocks and they were soundly priced.
If you are military or LE - I would suggest GT Distributors in Austin or Just Glocks in Copperas Cove (if you just want a Glock). Don't buy a gun locally when you can get it cheaper at a LE or MIL dealer...take the time to make the drive...you will save at least $50 on most common weapons.
