the guns seen in the Yakuza video game series.

I'm a gamer, and Yakuza/Judgment is one of my favorite series. In this series, I've noticed that virtually all the guns (which are usually semi-auto pistols) in cutscenes and as equipment have barrels that protrude out the muzzle, whether the barrel of the gun depicted is threaded or not. Anyone know why? Is this commonplace in Japan/Asia?
