Just bought a Victory. After reading forum I bought 2 #61 o-rings at our Ace Hardware. .49 cents each. Bought a box of 100 yellow drywall anchors at Home Depot, $3 and change. Installed one of the o-rings. Headed to our gun club range and shoot 200 rounds of Federal ammo. Just bulk stuff. Victory was flawless. Not one problem. Take down screw stayed tight, no loosing. Very accurate. I have Ruger mark I, mark III, and Browning Buckmark. Victory shoots as well as the Ruger and Browning. The drywall anchors work equally as well in the ruger and browning so I'm using them instead of empty .22 shells. I never have dry fired any of my guns without an empty shell in the chamber. Was taught that decades ago and still believe it. Thanks for the hints about o-ring and anchors.
