Odd grip and pic mount is horrible - Crimson Trace RIG Rapid Illumination Grip

Makes you use a weird grip. Light isn’t too bright with proprietary batteries. Feels more like a airsoft/generic Amazon light than something serious. Worst of all is the picatinny mount. You have to use a plastic spacer/adapter that relies on one screw to hold it to the mount and the screw is small so it can move in the space of the pic mount rails causing the whole thing to move and rattle back and forth. Mlok is very secure however. It should honestly be a 1/3 of the price. One of those things I regret buying.
