Scopes are for sniper rifles, not for handguns. (Well, you can put it on a handgun but whats the point when it doesn't have necessary long barrel anyway?)
You don't use
blasters in a hostage situations for the same reasons you don't use flamethrowers. Or shotguns. Or flamethrower shotguns. You also resolve hostage situations by "surgically shooting the bad guy in the head over the shoulder of the hostage" (if that's what you implied) only in stupid action movies.
Says a guy with no avatar that can't even write correctly. "U" is not a word. Neither is "r". You didn't delivered any proof that relative position of ironsights have any noticeable effect on an accuracy of a weapon that don't have sniper-like precision in the first place. To cite Wikipedia: "
Handguns are typically less accurate; at a shooting distance of 25 yd, a grouping is considered acceptable for
self-defense if the shots fall within a circle of 4 to 5 inches" That's 13 cm at 22 meters away. And that's for
firearms.
Although I'll admit that firearms are slightly more precise that I've envisioned.
