"The trigger mesh needs to be a separate object, to start with, then it needs to be attached to the trigger node. Easiest and fastest way to do that, in my opinion, is importing (or opening) the weapon in Blender or max (whatever you're using) and doing any modifications necessary. Then, simply re-export the model. Don't expect something awesome, though, if I remember right, in some anims, the trigger isn't animated at all and in others it's badly animated (it rotates slightly sideways). " Ok, thank you for your reply. I didn't think it would be an easy job, but still one I'm trying to attempt. I apologize for taking so long to thank you. I wasn't sure anyone would respond, and I'm grateful for your two cents.
