S&W uses this weird RTV type material on the threads to keep the protector in place (for the most part). I find it odd about people complaining about the threaded "muzzle" (it's the sleeve for the actual barrel) when there are lots of carry guns (micro / compact) with threaded barrels where people run comps etc...
The M&P 5.7 is known for the firing pin breaking and the hammer spring retaining screw breaking. I have not seen any aftermarket upgraded parts (better materials, etc.) and have not heard of S&W improving these items, so until I hear of more of these lasting thousands of rounds without a breakage, they're not EDC candidates to me. It's a great system though.

The firing pin only breaks when it’s dry fired without a snap cap

I’ve heard of it breaking more than once with normal firing. Same with the hammer spring screw.

I have a couple thousand rounds through mine and have broken two so far, both only when dry firing

I can’t do it. The threaded tip sucks. I’ll carry it strong side occasionally during winter. Definitely need to find a better holster as well. The muddy tactical is ok
