I don't think a stock gun, used as directed, should come apart in normal use after less than 200 rounds. The owners manual and a S&W video illustrate the proper procedure for taking the gun apart for cleaning, and putting it back together. They do not say anything about Loctite.
I torqued it down a bit tighter this time, so we'll have to see if it's a chronic issue, and if more owners have it.
Pretty much every optic mount, rail system, and other gun related item with a screw recommends a loctite type product. Every screw on front sight from Glock to Beretta to CZ recommends loctite. We even add loctite to the screws on our weapon mounted lights. Loctite is not like tig welding or something and one does not need to bathe the threads in the stuff. Just a dab will do.
