I just picked up a Gould & Goodrich shoulder rig for my Beretta 92/96 at the SHOT show for 60.00. I will be receiving my NV. CCW soon, and would like to know what is the proper setup with the holster. I know the gun should be horizontal, but how high should I carry the gun, and ammo, for that matter? There is plenty of adjustment in this rig, and I would like to hear everyone's opinion on this matter. Thanks!
