I wanted to search about unique and wierd guns or multifuncional rifles, pistols, shotguns etc. I did come across a very good post, Apache Gun Revolver, its basically a swiss knife of revolvers, a great old weapon which had a knife, a brass or metal knuckles and a revolver!

It's a very good design, I am sure if someone improves upon this, it can be a great selling item! Could make loads of money!  I would buy one for sure...

For more great posts, visit GadgTecs, the best technology site i've come across
