Animating:
look at the md3.cfg of the shotgun:
md3anim "gun idle" 0 1
md3anim "gun shoot" 8 25
Frames 8 - 25 hold the pump motion of the shotty. This is where you want to have your slide animation. Depending on how fast you want it, and when you want it to happen, it could be any of these frames (for example frame 8-16 or frame 12-20 or something).
For md3 export from blender, refer to the info found here: http://cube.wikispaces.com/
