The Sig Sauer store next door- owned by the same folks as AZ guns is fantastic and convenient if you're a Sig fanboy and likes to customize your guns. Has a lot of OEM parts from Sig online store at the same exact price. These items/ parts would cost an arm and a leg at the gunsmith or any other garden variety gun stop. I should know because I got the same exact item (parts kit for a P226/229) at C2 tactical down the street for 2x the price! The staff are all Sig armors and really knows their stuff. They even safety inspect your Sig firearms free of charge. When I need anything Sig- this is my go to store.
