I picked up my Victory a couple days ago. When taking it apart for initial cleaning I noticed there was a drop of Loctite, red nonetheless, already installed on the takedown screw. Ran about 100 rounds at the range. Didn't notice any loosening. If it does, I'll definitely install an 'O' ring.
BTW, so much fun to shoot. Looks much better than my former plinker, a Beretta NEOS.
