Recommend with a caveat - Rival Arms Guides Rod Assembly for Sig P365

So if you're willing to take it apart and clean it and put your own red loctite on it, it's a good product. They stuff they use inevitably comes off and you'll have to redo it, but now that I've put my own on with primer in it, it's holding great and works great. I've seen elsewhere other peoples having the same issue. So loctite without primer in it doesn't work on tungsten or stainless, which they seem to have used. Most threadlocker you buy in stores now has primer in it.
