Small weapon problem.
that can be annoying, but it can become easier. you might try the "Weapon Positioning On" in inieditor, see the appropriate section in the RF Ebook, it lets you (with numlock on) to use the numerical pad to change weapon offset in realtime. note youd want to change debug information to on in order to get the values it produces.
