Kydex Light Bearing Holster for Glock 48 MOS with Optic Cut

In this review the focus is on a left-hand inside-the-waistband Kydex holster built specifically for the Glock 48 MOS fitted with a Streamlight TLR-7 Sub or G43X MOS with TLR7X sub and an optic cut. The bottom line: this is for a left-handed concealed carrier who wants a durable, low-bulk holster that keeps an optic and weapon-mounted light secure while allowing a quick draw. The reviewer found the construction and fit to be the holster's strongest points, with the adjustable retention offering a useful balance between security and draw speed.

Key Features

• Custom Compatibility: Molded for Glock 48 MOS with Streamlight TLR-7 Sub or G43X MOS with TLR7X, ensuring a close, secure fit for those exact setups.
• Light Bearing Design: The cut accommodates the weapon-mounted light without forcing offset carry, so the light and optic remain usable while concealed.
• IWB Concealment: Inside-the-waistband profile is optimized to minimize printing and maintain concealment during everyday carry.
• Left-Hand Draw: Geometry and cant are set for natural left-handed draws, improving speed and ergonomics for left-handed shooters.
• Kydex Construction: Precision-formed Kydex keeps shape under use, delivers a smooth draw, and resists daily wear and moisture.
• Adjustable Retention: A settable retention system lets the user fine tune draw tension to match carry preference and garment thickness.

Who It's For

This holster is aimed at left-handed concealed carriers who use a Glock 48 MOS or G43X MOS with a Streamlight TLR-7 Sub or TLR7X under-rail light and who want an optic cut retained while carrying IWB. It suits anyone who prioritizes low bulk and durable materials for daily carry and values a customizable retention feel.

It is not intended for shooters who need ambidextrous carry, for right-handed users, or for owners of other pistol models without the MOS/light configuration. Competitors offering universal or soft-material holsters may be better for those who need flexible fit across several guns.

Pros & Cons
