Fallout New Vegas Armor Mod Help

[XxSHOTGUNxX]

I am looking for help me with fixing the meshes on an armor mod I have been using for awhile; I just can not get the hand meshes to hold the guns properly, the best I have done is I got the armor working in game only problem is that on some weapons the fingers are in the way when you scope in so I believe the issue is in blender with the hand and finger rigging or the hands may be too big altogether just wondering if anyone could help, I can send a file with all the textures and meshes I have. I know if I removed the 'see through scopes" mod this issues would not be a problem and I wouldn't need to worry about hand placement, but I really enjoy the mod. I have tried using blender but could never export my work and I know if I could decrease the hand size or actually line up the rig , the armor would hold the gun properly and be our of the way. As you can see in the pic the left hand is not holding the gun but floating around, if anyone is good at blender please let me know if you help, would be much appreciated.
