771 MAGAZINE POUCH, Adjustable Belt Loop. The 771 features two magazine tensioning screws on the back side of the holster that allow you to adjust tension on both the middle and end of the magazine - for just the right feel during draw. The magazine sits against plastic rollers that reduce drag even further during draw. And its open front design keeps your index finger from touching the holder during reload, assuring the fastest reload possible. The 771 uses an adjustable belt loop, Model 077BL. Adjustable to any angle with a 90 degree range and made from an injection-molded, high impact polymer, the belt loop can also be ordered separately in three sizes: 1.5" (38mm), 1.75" (45mm), and 2.25" (58mm). Available in STX Basket and STX Tactical. The 771 is also part of the ELS Competition Belt System. The 771 is available with the ELS 34 Locking Fork and the ELS 35 Receiver Plate (077BL not included). † Legal for the following competitions: USPSA OPEN, USPSA LIMITED, USPSA LIMITED 10, USPSA PRODUCTION, USPSA SINGLE STACK, STEEL CHALLENGE and BIANCHI CUP
