Glock 19 with Nightstick TCM-10 & TCM-15 OWB Holster

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

This outside-the-waistband (OWB) holster is engineered to fit 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. It delivers secure, consistent light-based retention for range use, training, and OWB carry.

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

Precision-Made for Performance

Each holster is vacuum-formed using a precision-machined mold created from an exact CAD model of the firearm and light combination. Every holster is formed, trimmed, and finished in-house, then test-fit with the actual pistol and light to ensure proper retention, smooth draw, and reliable performance.
