I have been using shoulder rigs for over 50 years. Bianchi 9R's (wore out 5 of them) and later Jackass rigs (the predecessor of Galco). The older screw in fasteners required some BLUE 242"lOCKTITE" and I always wore two per strap. Same deal with the new fasteners and still wear two per strap. GALCO is the only way to go at this point for comfortable and secure shoulder carry.
