Just bought a T/C omega Z5. I took to sight it in and after the 3rd shot the swinging breech will not stay up unless the hammer is in the cocked position.

It is Sunday! I asked the question to see if anyone has experienced this before. Logic would have called Thompson but like I said it is Sunday.

sorry my mistake.. forgot it was a weekend.

When ever something like that takes place the first thing I look for is any kind of foreign matter like 209 primer residue in the wrong place. It only takes a small piece to effect the entire way the mechanical part of the rifle functions. Then I look for crud or dirt build up in places it doesn't belong. I'm not saying that your rifle is not clean, but that is where I would look first.

I had one of my Knight rifles act up on me a fewweek ago. I looked that rifle over high and low and could not figure out why it was behaving the way it did. As a last resort, I took some break cleaner and sprayed out the trigger assembly, then took an air hose and blew it dry. After that I oiled it lightly and put the rifle back together again.. low and behold, worked like new.

That's the first place I would look. I will be interesting to learn what might be the problem.
