These places usually have guns you can buy right off the shelf; however, most folks who can afford such rarly by off the shelf. They go in an just like buying a fine suit, they have tailors there who take all your measurements to fit the gun to you personally. During my time in Germany with the US Army, I went to a couple of these store's to have a look. Business casual is minimum allowed that will get you in. You can't just stroll in off the street in jeans and t-shirt, they'll turn you around at the door. The one in Frankfurt will let you handle, but they will issue you a pair of white cotton gloves. Regardless of how you'd feel about this, its still a cool place to visit, its makes someplace like BassPro look like WalMart.
