I've never been to a gun show before. Tomorrow we are planning to go to one. So -- for the gun show newbie, what kind of great deals should I be looking for??? I don't want a new gun. I just bought my G19. But I know I could use a better range bag; and I've heard that ammo an be cheap at these sales. What kinds of things do I watch for in choosing ammo? What other things do they sell at these shows that are extraordinary deals? All help appreciated!!!
