Pro Sports in Eureka has a sign on the door saying ALL guns to be unloaded upon entering, but the guys who work there have no problem with those of us who have CCW permits carrying. Just keep 'em concealed.
I bought my Ruger 45 there and they were pretty helpful.
The 5th Street Shootery has a similar sign on the door but is ok with us carrying too. He also has a 50' indoor pistol range.
