A realistic sense is "Metal Gear Solid 3"?wildweasel wrote:In a realistic sense, some use this method to create a horizontal jump from the recoil, allowing them to spray a room sideways with well-timed presses of the trigger and minimal effort to move the arm. EVA from Metal Gear Solid 3 uses this tactic with an imitation Mauser 9mm handgun, though the principle is the same for recoil-operated handguns, I would imagine.

Come on, it's all just posing and bullshit. It's an unstable, stupid way to hold a weapon. You should hear my friend's army sergeant-major wax-lyrical about just how "f*cking stupid those f*cking c*nts" who hold a weapon like that are Or another friend of a friend (who is a cop in the US) go on about how many innocent by-standers get hit by gang-bangers who "know" the best way to hold a gun is sideways.
Yeah, on the laser sight thing (the black cylinder with the red dot), it looks like it is on the left of the weapon in the normal position but when the weapon is held sideways - then it's apparently on the right-hand side.
Akimbo - originally used to mean standing with hands on hips - elbows outward. Tends to be used in fps games to describe holding 2 weapons - one in each hand. Not holding one pistol sideways.
