If your Glock G48 MOS has a tac rail.. then YES... the Nightstick TSM-14G is the model you are looking for. If no tac rail.. then go with the Nightstick TSM-11G. Both models are magnetic couple charging, so the USB cord plugs into your power source... and the magnet snaps to the charging port at the bottom of the light so you don't have to take the light off the weapon to charge. Just make sure the weapon is charged in a safe with a portable battery charger, or use the included cable lock. Hope this helps.
