Ive been purchasing my ammo from Wal-mart since Ive owned my gun. I always get the Federal's in a 115 grain for 9.97 for a box of 50. Its been great ammo so far, my sig eats like a Fat Kid at Golden Corral. I'm not complaining but I have yet to find an online retailer able to sell at that price! with tax it comes to $10.60 a box. With the online stores you also have to pay shipping to so thats a factor. This ammo is just for the range.
