Fits Glock 48 IWB Concealed Carry Holster - Base Model

In this review the CYA Supply Co. Base IWB Concealed Carry Holster is evaluated as a dedicated inside-the-waistband option for owners of the Glock 48 or Glock 48 MOS who need a slim, dependable carry rig. The bottom line: this holster is for concealed carriers who prioritize a low-profile fit, adjustable retention and a full-length sweat guard that protects the slide; its CAD-milled precision and durable 0.08' Boltaron construction deliver a consistent draw and re-holster experience without wasting features on light or optic compatibility.

Key Features

• Exact fit: Molded from CAD patterns to precisely fit Glock 48 and Glock 48 MOS frames, offering secure contact and minimal movement on the draw.
• Adjustable carry: Retention pressure and cant are easily adjusted from 0 to 15 degrees so users can fine tune draw speed and concealment angle.
• Durable materials: Constructed from 0.08' Boltaron material with stainless steel, black powder coat hardware for long-term wear resistance.
• Posi-Click retention: Audible lock system provides a clear engagement cue so you know the pistol is secured in the holster.
• Sweat protection: Full-length sweat guard covers the slide to reduce moisture contact and minimize wear on the firearm finish.
• Made in USA: CNC milled in house with a lifetime warranty and a no-questions-asked return policy backing quality and customer satisfaction.

Who It's For

This holster suits concealed carriers who own a Glock 48 or Glock 48 MOS and do not plan to use a red dot, light, or laser attachment, since the design explicitly excludes optic and light compatibility. It works well for everyday carry where clothing is slim or summer carry in shorts is preferred, offering a low profile and reliable retention.

Those who need optic-ready systems, light-bearing setups, or a different carry location (outside-the-waistband, chest or ankle) should look elsewhere; this model is intentionally focused on a clean IWB solution with simple, robust features rather than modular accessory options.

Pros & Cons

Pros

• Solid build quality and precise CAD-to-CNC molding create a consistent, smooth draw and re-holster.

• Full-length sweat guard and quality materials protect the firearm from moisture and abrasion.
• Made in USA with a lifetime warranty and clear return policy adds confidence to the purchase.

Cons
