Does the gun have double triggers, or single? If a single, be very careful not to over tighten the screw, also (I believe) sometimes referred to as the hand pin.
I second the use of blue Loctite. Don't use the red anyplace you can't apply heat to get it to release.
The hand pin is the pin that threads upward from the trigger plate into the rear of top tang. The hand pin head is usually hidden underneath the trigger guard tang, the end of the pin is filed flush with the top tang.
All of those pins should be tight. Those are the pins that hold your stock onto the gun. Loose breech and hand pins equal cracked stocks. I’ve never dealt with LC Smiths with HOT, so I don’t know about those, seems odd that you can’t tighten a pin down because it interferes with the operation of a trigger. What a quirk.
