I'm new here and new to B&T ownership. Got my 1st one a couple months back. Question, I picked up a GHM45 with a folder brace and wanted to go with a collapsible. Found one that was said to fit on these GHM's, 9/10/45. got it swapped out and it seems to pinch up when collapsed. I'm thinking Bad info on what it fit or maybe I need to change out the tail piece? Input?
