Mostly I mean you can arm an army online if you have the cash.
Oh and I used to have a S&W .44 magnum with Pachmyr combat grips. Man that was a fun gun!
Got rid of it at the local pawn for rent money back in '97 intending to buy back. I never did. A lesson learned, I'll never pawn any of my stuff no matter what I owe. I'll file bankruptcy first.
There is a gun distributer located in AZ called Gallery of Guns, website galleryofguns.com. I have only looked at them thus far and may use them in the near future. They can acquire any gun commercially made or imported to the United States. They then quote the manufacturers suggested retail. Then with your zip code will come up with 3 local gun shops with their best deal. You can save hundreds of dollars off retail depending on the gun you have in mind. They also sell gun accesseries and have product videos.
This is how I'll get my 1911 and I think I want a Desert Eagle and maybe another .44 and maybe an AR15 style rifle at some point.

I am not the best shot, nor am I the worst. I think I will kill what I'm aiming at however.
