The 6360 ALS/SLS Mid-ride duty holster is sturdy, lightweight, and provides an extra measure of security while on patrol. The ALS (Automatic Locking System) builds on the foundation of the SLS (Self Locking System) to offer Level 2I Retention(TM). In addition to the SLS, Safariland's patented ALS locks the firearm into place immediately upon holstering, while the rotating hood and tension device ensure added security. The 6360 holster can be easily upgraded to Level IV Retention using the optional Sentry attachment. The 6360 ALS(R)/SLS Mid-ride is constructed of durable SafariLaminate and is lined with suede to protect the gun's sights and finish. For a snug and comfortable fit, the mid-ride belt loop allows the holster to ride close to the body.
