For target or self defense ammo? For target, they are all about the same. One of the best deals you can find these days without reloading is the Federal 9mm at Wal-Mart, $9.50 a box, or the Rem 250 packs for ~$50. For self defense, and staying with the reasonably priced thing, I would get a box of Winchester white box JHP 50 rds. You can shoot some of the rounds to function test in your pistol and still have plenty left to load your magazines. Other than that, any of the non +P premium self defense ammo would serve you quite well, such as Gold Dot.
