If you're going to become a competitive shooter, the 1911's are worth
looking atr. If you're goping to be a plinker and want a defensive
weapon, get the Glock. It's absolutely reliable, carries a high
capacity magazine and is cheap (relatively speaking). Get it in 9mm
because, as Harry says, the ammo is cheap. And you may be able to get
one used as a police trade-in. If you're keeping it at home as a
defensive weapon, buy the frangible rounds. They're designed to break
up on impact. They'll probably kill anyone you hit, but they won't go
through the drywall and kill someone you didn't intend to shoot. And
get the lessons. They'll help you to stay safe and keep everyone
around you safe. And you'll learn how to hit what you're aiming at.
