I noticed that Sports Authority isn't on your list. So, guess I can't vote!
It's been my experience that there is no store here with consistently "best deals." Each has something that the others lack, each runs their own specials. Well. each except Magnum.
I think anyone who proclaims "Bob's guns has the best prices and that's as far as I bother to go" is doing Bob a huge favor and themselves a huge disservice. I won't shop at Magnum, they worked hard to see to that. I've yet to go to OGC, but hope to remedy that mañana. The others, I circulate between whenever I am in the neighborhood. If I am looking for something specific, I pick up the phone and call them all. And, I can tell you after about 13 years of doing that here, there is no consistent winner. All of 'em have their good days, and all of 'em don't.
If it were purely based on friendship, Kaneohe Gun Shop would get all my custom. Daniel cuts his prices to the bone for me. But, sometimes cutting to the bone isn't as good a deal as what Young Guns has in their used case, or Gun Source has on sale. And no one but no one touches Sports Authority's prices when they run sales. So I have friends, and I like gun shops, but as has been said earlier, I vote with my wallet.
