The Safariland Model 7378 7TS ALS Concealment Holster built for the Glock 21 (brand part no. 737838327412) is a left-hand outside-the-waistband holster designed for concealed carry rather than open duty use. Safariland molds the 7378 from SafariSeven, a durable, non-marking nylon blend engineered to resist heat, cold, and moisture without scratching or marring the pistol’s finish, and pairs it with the same Automatic Locking System (ALS) used on Safariland’s duty holsters for genuine Level I active retention in a slimmer concealment profile. The holster mounts via paddle or belt loop for flexible carry options. Among holsters and gun leather, the 7378 suits Glock 21 owners who want duty-grade retention in a holster built for concealed rather than uniformed carry.
