I don't claim to be a gun expert, however, one thing that annoys me is when gamers label certain first and third person shooters as being realistic. They may indeed be more realistic than other games that use guns, but let's get this straight, there is no such thing as a 100% realistic shooter in gaming when it comes to guns.
That's why it annoys me when some gamers knock a game for "not having realistic gun physics."
