I bet you would be thinking that I would be suggesting a rifle. Nope!
One of the best defense guns on the market is the ubiquitous Remington Model 870 12 Gage Pump, fitted with a smooth slug barrel and it serves a dual investment.
You can hunt deer with it too. It is not just sitting locked up in the corner of the bedroom gathering dust. Just remember store it safely so it will be ready for home protection after you are done.
I have had an 870 pump for most of my adult life. It has served me very well for deer, turkey and ducks and makes a statement if pointed at an intruder or it is cocked with that characteristic kachunk-kachunk movement of the slide down and back up. On the wrong end, hearing that will certainly suggest that you are in deep do-doo as an intruder.
If loaded with a round of 00 buckshot, it meets the FBI minimum penetration criteria. Slugs will penetrate much further and injure others in far off rooms. Shoot a 00 buck load and you have unleashed 8 .33 caliber pellets at the target in just one shot and will penetrate a wall or door to do it.
I like the 45ACP Pistol but if I were really concerned over local break-ins you can bet both would be ready. © 2013
