Safariland Model ALS/SLS Mid-Ride Level-III Duty Holster Glock 31/Glock 17/Glock 22 Left Hand Basketweave Black. The holster's position in the mid-ride position allows the gun to be quickly drawn without hassling the gun. The 6360 holster combines two separate locking systems into one unit featuring an Automatic Locking System (ALS) that locks the firearm into the holster when holstered and a Self Locking System (SLS) that engages the firearm upon holstering with a slim compact design that allows the weapon to ride close to the body. With both systems working together they ensure the holster stays open while preventing the firearm from being holstered. With both systems active only slightly pressure is needed to release the holster and the hood of the holster stays open for the draw. The mid-ride position allows the gun to draw quickly while the rotating hood locks the firearm into place once holstered creating an even faster draw. The 6360 ALS/SLS Mid-Ride Level-III Retention Duty Holster is designed to ride close to the body to keep the gun from moving while holstered.
