6378RDS Concealment Paddle Holster for GLOCK 17/22 - RDS Ready

In this review of the 6378RDS concealment paddle holster the bottom line is simple: it is for shooters who run a GLOCK 17 or 22 with a red dot and a Streamlight-style weapon light and need dependable everyday retention and quick access. The reviewer found the holster delivers a secure Level 1 ALS locking system and a thoughtful protective RDS cover that rotates out of the way during the draw. Overall it reads as a practical, no-nonsense concealment option for duty or carry when a red dot optic and light are fitted.

Key Features

• RDS Compatibility: Designed specifically for red dot optic equipped weapons, so pistols with an RDS sit correctly and draw smoothly.
• Light Fitment: Mated to Streamlight TLR 2 style lights, ensuring the light and holster clear each other without added modification.
• ALS Locking System: The active locking system provides Level 1 security that retains the weapon until a deliberate draw is made.
• Protective RDS Cover: A built-in cover protects the red dot lens from impact and automatically rotates out of the way when the pistol is drawn.
• Mounting Options: Comes with a larger flex paddle and an optional fully adjustable belt slide that fits 1.5' to 1.75' belts for multiple carry styles.
• Durability and Protection: Built to hold up with solid retention and coverage, offering long-term protection of the optic and light on daily carry guns.

Who It's For

This holster is aimed at owners of GLOCK 17 or 22 models who run a Streamlight TLR 2 style weapon light and a small red dot optic. It suits both duty users and everyday carriers who want a lockable concealment paddle with the option to switch to a belt slide for more secure mounting.

Those who should look elsewhere include shooters without a red dot or weapon light, or users of very small framed pistols not listed as fits; also consider a dedicated appendix or inside-the-waistband model if deep concealment and minimal footprint are top priorities.
