Description

The 6378RDS ALS Open-Top Paddle Outside-the-Waistband (OWB) Holster combines the accessible design of an open-top paddle holster with the security of ALS. The Safariland Model 6378RDS Holster is specifically designed for firearms with red dot sights and made for the rigors of daily use. ALS locks the firearm securely in place when holstered, but still allows a natural draw with a swipe of the thumb release as you establish your grip. SafariLaminate construction makes the holster strong on the outside, while SafariSuede on the inside protects your firearm’s front sight and finish. The Model 6378 comes with both the paddle attachment and a standard belt loop, making this holster as versatile as it is functional. ** Safariland cannot assure that RDS holsters will be compatible with non-factory (Glock MOS, M&P CORE, etc.) mounted red dots. Numerous variables including depth of RDS into slide, use of dovetail, placement on slide, etc. can all affect the fit of the holster. This holster is not compatible with the Trijicon SRO optic.

A Little Pricey, But Secure
Color: STX Tactical Black Size: GLOCK 19MOS X300U Style: Tactical
Fits my G45 with optic and TRL-1. A little pricey, but secure. Typical for Safariland.

Great Holster
Color: STX Tactical Black Size: GLOCK 19MOS X300U Style: Tactical
The holster is great, easy draw and easy to reholster. Came with a bit of scuffs so I wasn’t too happy about it but overall i’m very happy with its performance.

Doesn't fit Glock 10 Gen 5 MOS
Color: STX Tactical Black Size: GLOCK 19MOS X300U Style: Tactical
I have used Safariland products for years and love them, but this holster does not fit a Glock 19 Gen 5 MOS. The lateral clearance on the sides of the slide are to small making unholstering/reholstering difficult and leaving contact marks on the top left side of the weapon slide rail. None of my other Safariland products have ever done this. Very disappointing. ... show more
