I want to get started in a local competition that follows USPSA rules and guidelines. I have a stock Glock 22. What modifications should I make and where's a good place to get parts? I'm talking about extended mag release, sights, mag related items, etc. I've seen mods such as mag wells, tungsten guide rods, 3.5# connectors, etc. I'm looking into either the Kytac 1 or the Kytac Sooper Hooper as my holster. I know the Kytac 1 is illegal for IPSC but I believe it's ok for USPSA. Also, would the WWB 180gr ammo be ok? Wal-Mart has the 100rd box at a reasonable price. Any help would be greatly appreciated. -DRe.
