It fits other rail mounted device, too - BlackHawk Level 3 SERPA Duty Holster

If you don't have the Xiphos Weapon Light like me. It will also fit a Beretta Genesis Green Laser. Just make sure you loosen the front screw on the Holster or remove it. Otherwise it may drain (sometimes switch hitting against the Holster wall inside) the rechargeable battery on the Genesis. Also disengage the safety on the M&P 45, otherwise the hood won't latch / close.
