Now I will have to go look again. I think it opens fully, but perhaps it does hit on the lugs. I know that it opens at least as wide as an old style contender. Perhaps I need to do a little trimming.
After checking I see opening wouldn't be the problem. It would have interfered with just putting the forend on the frame.
Mine fits. I don't know what has changed. I bought this forend used, and the previous owner may have changed it. If so he did a beautiful job. Perhaps there are different lengths of side panels on 10" forends, and I got lucky. Perhaps T/C shortened the ears on G2s.
Bottom line is my previous post has to change. Your forend may work, or it may have to be modified. If anyone knows what the difference is between mine and others please post.
Thanks
