Glocks have the "Glock Smile", and I am sure that other guns have them as well. When a bullet is fired there is intense pressure created. The pressure is what makes the bullet fly out of the barrel. More pressure = more velocity. That same pressure tries to expand the brass, but the chamber stops it from expanding to the point where it splits. The smile comes from a void or open space in the chamber. This void creates the smile because the brass expands to fill that void.
