I bought a Victory last Friday. Have had it to the range 3 times and 400 rounds of 7 brands of ammo. Take down screw was tight, but did break loose with just an ordinary allen wrench. It has never come loose during shooting. (last range session was 200 rounds). I do use some "anti-seize" on the threads and I torque to 35 in lbs.
I did have ejection issues for the first 100 rounds. I "tweaked" the ejector and have not had a problem since.
I do like this better than my 22/45 lite. Accuracy is about the same.
