The lug holding the trigger group and the front barrel lug on my Omega X7 are both secured to the barrel with T8 Torx screws; two screws on each unit.

I recently had the front lug become very slightly loose for the second time. Not much, but I could detect a tiny movement that went away when I tightened the screws again (even though I could feel no movement of the screws when I tried to turn them).

Here's what the assemblies look like.





I haven't applied Loctite to them and was getting ready to do that when I got to thinking about alternatives. I know gun makers use silver solder to secure barrels and ribs on double shotguns, so it must have pretty good holding power. Also, it doesn't require the high degree of heat involved in welding.

So the question is this. Can I flood the areas between that stainless barrel and the carbon steel blocks with silver solder and expect it to hold? Would using Loctite on the screws be just as effective?
