Yesterday I found this little thing:
When you export v_WEAPON_hand.md3 using Tical’s exporter (the one packed with Pants’ guide), you get a dialogue asking you for the frame range you want to export.
Ok, let’s say you have 66 frames, like the original thompson, going from 0 to 66.
In order to export correctly and actually use the same frame numbers, you need to export the frames from 1 to 67.
If you export from 0 to 66, then you get 1 frame less and 1 frame difference: For example, if you made an animation starting on frame 50, then you’ll need to set it as frame 51 in weapon.cfg.
And so on, if you have x frames, you need to export from frame 1 to frame (x+1). And only then can you work with frames 0 to x inside weapon.cfg.
So, Pants 
Feel free to include this inside your guide if you think it’s useful.
