One grip screw as well as the thread protector on my Tanfoglio Witness keep coming loose after some rounds on the range. I tried blue Loktite but they still came loose. I see the red flavor is considered "permanent" but how permanent is "permanent"? Is there anything in between or do I just have to accept if I ever want to remove them after using red flavor it'll be a pain or just deal with stuff coming loose without?
On a related note, would blue flavor hold up better on a 5.56 muzzle device for my Tavor?
