Replace the Glock 48/43X/48 MOS/43X MOS magazine base plate with a rail adapter so you can attach the MantisX to your G48/G43X/48 MOS/43X MOS.  

Preferred if you don't have a light-accommodating holster and want to train with holster draws, or if the firearm doesn't have a rail.

Part number: MT-2065
