Nothing wrong with using the correct threadlocker the right way. It can be a very useful thing, done right. Done wrong, not so much, and possibly even a problem.
As I posted earlier I've had good results with "Guntite". In the distant past I've even used enamel model paint or the wife's fingernail polish to lock screws in place, or serve as a tell tale to show if they have moved. All that really matters is you use something (IF NEEDED) that keeps the screws from moving and that YOU can remove the screws normally when you need to.
Something to watch for, if you shoot revolvers, is screw tightness. Something about revolvers vibration tends to loosen screws. Bit of an eye opener when a screw that you tightened, and that still looks tight goes a part of a turn when you check it with a screwdriver.
Old revolver shooters learned it was SOP to check ALL the screws for tightness, before taking the gun out to use. It think its a good practice to have properly fitting gun screwdrives and check ALL screws on anything for tightness every time the gun is removed from storage, before use.
You MAY never find a loose screw. But the first time you do, you'll realize the wisdom of checking. (and, "checking" is not reefing on the screw as hard as you can to tighten it more...
)
