front sight woes

[WDE91]

I recently bought a new Ruger 22/45 5.5" blued target model

The front sight managed to wiggle itself loose
I removed the screw and saw that there is red loctite on the threads

How should I go about removing the red loctite?
What should I use to make sure it stays in place

Thank for your help

I'de just add some blue locktite to it and screw it back in.

I went ahead and did that

My plan was to torch off the red loctite,mix up some epoxy,red loctite on screw and epoxy on sight base...
