Checked after posting, and both trigger groups are numbered to the gun just like both barrel sets. based on how complete the rig is and everything matching and having the spare parts kit and original case, i'm going to assume the spare group is set up to fire the top barrel first. Will try them both tonight.

I think before i send anything to anybody i'll figure out if i even have a problem but i really doubt i do. i know the group that was in the gun when i bought it fires the bottom first.
