I am restoring a single trigger Tobin 12 gauge SXS and i found that a part of the trigger group is missing. There is a small part that I have no idea what it is that is missing, you can see the screw hole and there is a spring that is supposed to interact with the missing piece. I do not know what it looks like or what its function is in the trigger group.
If anyone has a single trigger and can provide a picture of the missing part or if someone can tell me the function of the missing part I would appreciate it.
The trigger appears to function just fine without it.
