Getting a grip - Magpul Industries M-LOK MVG Vertical Grip

The M-LOK version is either shorter, less girth or both compared to the picatinny version. Feels like your pinky at times wants to move under when grabbing. The equivalent would be gripping a baseball bat, then going to a golf club. It is solid and works well, just is noticeably different when going from picatinny version to MLOK version.
