Couple of things here.
1. Is this the first gun you have ever owned?
2. Do you have ANY experiance with firing a gun?
3. How many people are living in your home with you and what type of home do you live in? Apartment, house, condo?
I ask all this because for a new gun owner it's important that you make the right choice when purchasing a firearm for a specific purpose.
Personaly I would NEVER recomend a handgun for HOME defense. Couple of reasons for this. Handguns take more training to become proficient with. In the event you might actually need it, if you are not 100% sure of your own ablities to handle the weapon and hit your target the very first time, you have problems. A handgun fires a round that can and WILL penetrate the walls in most homes, and will still be deadly to anyone on the other side of the wall. If you miss, you can put everyone else in your home in danger.
I've owned all sorts of guns since I was 14 years old. My personal choice for home defense is a 12 gage pump action shotgun loaded with #4 game loads. The reason I recomend a shotgun is you don't have to be 100% accurate in the heat of the moment. Close is often good enough. Light game loads do NOT carry enough energy through a wall to seriously hurt someone on the other side if it does penetrate, but they will put someone down with a direct hit. Last but not least, a criminal even hears the sound of a pump gun being racked, he knows he's on the receiving end of some very bad news.
A decent shotgun such as a Remington 870 is going to be several hundred dollars cheaper to buy than a good reliable handgun, as well as the ammo being cheaper and more easy to come by. Check around your local area for Trap and Skeet ranges. Learning to shoot a shotgun at small moving targets is the BEST way to learn proper lead, plus it's fun as hell.
Don't limit yourself to a gun your only going to keep locked up in a safe. Get something that you can take out and shoot on a regular basis and have fun with. I've yet to go to a Trap range and not have a great time and meet nice people.
Hanguns are nice but they have their limitations. For a first gun I think a good shotgun will serve you better. They're just easier to use and to get comfortable with. If it's something your wife or girlfriend might have to use, maybe a 20 gage. Something with a little less recoil, but still has plenty of knock down power.
Remington, Wichester, Mossberg, and Bareta all make pump action shotguns in what they call a "Home Defender" model. Short barrel, and a shortened stock. Most are priced anywhere from $300-600 on average. Ammo will run about $4-6 for a box of 25 shells.
Good luck and welcome to the club.
