I just picked up a new FNX .45 a couple days ago, and love it so far! It's pretty soft shooting, and not as big as I was expecting. Really thrilled with the purchase. I do have a question though. I have a Surefire x300 Ultra weapon light. It has the universal latch installed, but the pistol has a picatinny rail system. I do not have the Picatinny latch for the weapon. Will I be able to use the light on the pistol with the universal latch installed?
