Ammo prices suck for 357 sig. The cheapest I have found for a 50rd box was like $17 at a gun show. You can get bulk buys (like posted above) and quality copper reloads for cheaper. You can also reload it pretty cheaply. Or you can just get a 40s&w barrel and play with the cheaper stuff and carry the 357 for protection or when you want to shoot some hot stuff. Also, it is kind of nice to have something a bit different than everyone else.
