I deal with all of them to some extent. I buy reloading components at SW, ammo at Diamondbacks, (and a used gun a year) but lately I make the rounds of Frontier gun shop, (I'v visited him twice a year since 1959 and he gets great deals on older stuff with a once in a while deal on a Sig or something he has taken in on trade) 2nd Ammendment (Jensons) then across the street a bit is the new Pima Pawn that is a nice Tactical store specalizing in black stuff. But the gun store with most of the goodies is a frirly new on on Broadway and near Pantano, Tucson Guns and Western Artifacts. Black section, anitque section, hunter section, more and more reloading components. Oh also Slash K on Ajo road roe re-laofing stuff. My suggeston to all, get into reloading.
