Considering installing an XS Big Dot sight on a M&P 9C. My concern is the need for locktite on the rear sight.
I have this sight on a couple firearms and the directions say to use the locktite product, so I assume the 9C will be the same.

If I use the locktite can it later be removed to replace the striker safety plunger or the safety plunger spring.

I suppose the next question should be "How often does the spring need replaced?"
