Comes lose - Griffin Armament Micro Carry Comp 1/2x28

I have the compensator on a Sig Sauer P365. Comp get loose when barrel gets hot. Other than that, I like it. Just have to remember to snug it back up after emptying each mag. I do that jut by hand. Yes, I tightened it up really good in a vice the first time and it loosens up at the shooting range l had the gun smith also tighten it up at the shooting range and it came loose again, did not put locktite on the threads because I like to be able to take apart the slide easily. It does take some of the snappiness out of the recoil.
