Glock 19 with Nightstick TCM-10 & TCM-15 Duty & Competition Holster

Glock 19 / 19X / 45 Duty & Competition Holster – Nightstick TCM-10 & TCM-15 Compatible

This duty and competition outside-the-waistband (OWB) holster is purpose-built for the Glock 19 Gen 5 and Gen V, Glock 19X, and Glock 45 Gen 5 and Gen V when equipped with a Nightstick TCM-10 or TCM-15 weapon-mounted light. Designed for training, competition, and duty use, it delivers consistent light-based retention, fast presentation, and reliable performance.

Important: Retention is achieved on the weapon light itself—not the pistol. This holster will not function properly without a compatible Nightstick light installed.
