So My Victory is about 2 months old and has about 700 to 1000 rounds on it. I had an issue with the screw coming loose after 100 rounds or less. Not the set screw but the takedown screw. I also had an issue with the part on the barrel coming loose. I used purple loctit on that. I did put a tiny amount on the screw after I cleaned it last. Today I go to the range and after about 30 rounds the barrel flew off with no warning of any problem after I picked up all the pieces I found that the screw broke off in the barrel in just about half. The piece in the bung was not tight at all it turned right out. The threads show no sign of being over tightened or being cracked. It just failed! I will try to post a picture of it later. S&W said oh no problem we will send you a new one? I am less than happy and I loved it right up to this..
