Alas, Jack, you've asked the wrong guy. This is one of the many moments when I wish JR still had time to do the Glock Pistols section at GATE.
If GATE was about cars instead of guns, I'd be one of the driving instructors, not one of the mechanics or engineers. Which Loc-Tite is something I leave to the armorers and gunsmiths.
Suggest you try in General Glocking.
Wishing I could have been more help,
