Well, I purchased 100 more rounds of the Blazer Brass ammo for my XD40. That is some really nice ammunition for the price. It's got brass casings for the folks who like to reload, the primers are pretty nice, too. Most folks know Blazer as the ammo with the aluminum cases that don't always feed so well in their guns. These cases aren't aluminum, so there's less worry about getting a casing stuck while trying to eject it from the gun. At 180 grains in weight, these are pretty hefty bullets as far as .40S&W goes. If you're looking for decent factory ammo, though, take a look at Blazer Brass. It's good stuff.
Once my aim gets better, I'll start using the various personal defense rounds to see how they shoot through my gun.
