Glock 34 IWB Holster

Inside Waistband Holster for Glock 34 Gen 5

This Inside Waistband (IWB) holster is precision-molded to fit the Glock 34 Gen 5. Each holster is formed, tested, and finalized using a Gen 5 Glock 34, ensuring optimal retention and draw consistency.

If you are using a Gen 3 or Gen 4 Glock 34, the holster will still fit, but we recommend making a slight retention adjustment upon receipt to achieve the ideal feel and security.

Product Highlights:

• Fits Glock 34 Gen 5 (compatible with Gen 3 & 4 with minor adjustment)
• Full sweat guard for comfort and slide protection
• Adjustable cant and retention for a tailored fit
• Optional Modwing for reduced printing—includes 2 insert options
• Minimalist footprint with smooth edges for enhanced concealment
• Made from rigid, .093" thermoplastic for long-term durability
• Vacuum-formed from CNC-machined molds and tested with the actual firearm
• Proudly made in the USA

Maintenance Tip:

To prevent screws from loosening during use, we strongly recommend applying a removable thread locker such as blue Loctite after setup.
