I'm so dense, I can't believe I'm not committed...

I'm using the cbabe.mdl (test purposes only) and a gun model (placed on the ground to be picked up). Both have been scaled to proportion correctly. Now, when I pick up the gun, in 1st person mode it appears way over on the right and to the bottom of the screen and I'm stuffing around with the x/y/z origins which doesn't seem to move it. Also in 3rd person or static cam mode, the gun appears between her legs!! I guess this is the centre of the player model.

This happens with any gun I give her. I want the gun to be dead centre and just down a bit from the crosshair in 1st person and hopefully in her hand in 3rd person, but I don't know how to do that and I can't find anything relating to it in the forum. Can anybody help me with this? Thanks in advance.
