Locking screws walk out - Faxon Firearms EXOS-524 Pistol Compensator for M&P Shield/Shield Plus

Works as a comp, but the set screws walk out leaving lock tite to do the work, red is a must making cleaning more annoying. Does mitigate recoil but use +p or hotter range ammo or it won't cycle properly. Even 124 blazer will give a few f2f per mag and last round hold open won't work in that situation either, don't bother with 115.
