What do you use for home defense rounds? Hollow points are recommended because they mushroom and break up into pieces easier than FMJ, so they don't go punching through walls as easily. Cuts down on the risk of strays hitting someone.

Also, accuracy is more determined by factors such as your skill level, barrel length and ammunition used as opposed to the type of gun, unless there are manufacturing defects. Glocks are popular because they are guns for dummies... uh, I mean "people that own but don't care to learn about what they own", not so much because their accuracy.
