Do your self a favor and get some thing you can depend on it when a group of 20 men arm to the teeth roam your street burning and looting
you may need at list 2 or 3 - 30 bullet magazines a shotgun or a hand gun will be just a toy
never mine if the taliban get their hands on a nuke and nock out our communication centers
Be sure to find a gun with a trigger pull you like. Some revolvers and the Rugers have longer pulls vs the Glocks, etc. I will be trading in my Ruger LC9 because I could not adjust to the long trigger pull.
IMO this debate has people buying guns because the fear that Obama will limit what is availible. But also, it seems that it has raised an interest in the sport which will drive more sales. The great "gun bubble" may not appear.
I highly recommend taking a decent class in whatever you're considering purchasing. It will save you a lot of time and expense in terms of figuring out what your preferences are, to saving time and money by not trying to figure things out on your own or from a book.
