Remix of my original M-Lok grip, but for 1913 rails. Big thank you to FFFTechnology for the picatinny rail and mount models (see "This remix is based on" area below for links). 
 

Print Orientation

The model is oriented in the correct position (upright at an angle with the back face down). Orienting the model this way will only require supports for the first overhang. See photo above for reference.

Hardware

Utilizes (2) M5 30mm bolts and (2) matching M5 nuts.
