The Safariland Model 7378 7TS ALS concealment paddle and belt loop combo holster features an Automatic Locking System (ALS) for securing a weapon upon holstering, which can then be quickly drawn with a thumb release. The holster has an open-top design for fast retrieval without the ALS. Constructed from SafariSeven, a proprietary non-abrasive nylon blend, it is designed to not damage the firearm's finish and to withstand extreme temperature ranges. Raised stand-off surfaces inside allow for quick clearing of dirt and moisture.
