I have a new Omega stainless with black thumbhole
stock. After reading your post I took mine out of
the gun cabnet. I do not have the problem you show
that you do. But after a through cleaning I use an
old scope lens cloth with rem oil and apply to the
trigger guard and trigger assembly. Like you stated,
Thompson Center, will makke it right. They have, I
think, the best customer service bar none. Hope
you get your problem solved. Danny
