I am looking for some assistance with a problem of my own making. I was in process of disassembling my SBE2 and needed a refresher, so I was watching the first of a three part Benelli video. Once I had the pin out, it instructed to pull back and down on the trigger guard to remove. It did not say to push in the carrier button while doing so, like I said I needed a refresher. Now my trigger guard assembly is stuck and may be hung up on the internal workings of the carrier button. I have tried to manually manipulate these internal working, but can’t get it free; nor can I get it back into place to start over. It don’t want to force anything. I would greatly appreciate any help anyone can provide! Thank you very much!
