RHC,
I live about 20 miles north of Kerrville, and find that Arrowhead has the best selection, and Hill Country Arms has the best prices. They also order stuff at reasonable prices. There is a gunshow in Kerrville every other weekend, and in Fredericksburg the other weekends. My suggestion to you though is to drive out towards Hunt on Hwy 39, and go enjoy the cool waters of the Guadalupe river crossings. You can go to gunstores anywhere, and Kerrville isn't exactly a firearm mecca. So enjoy yourself in the river. You won't regret it.
