Flex Master Blaster Modular Appendix Holster

The Flex Master Blaster is a modular appendix carry holster built for those who refuse to compromise. Designed to give you the comfort and capacity of a sidecar holster with the flexibility of a standalone concealed carry setup, the Flex Master Blaster adapts to your needs in seconds.

Run it as a complete AIWB sidecar holster with an integrated magazine carrier for maximum capability and everyday readiness. When you want a lighter setup, simply separate the magazine carrier and convert the holster into our proven Valkyrie IWB holster. One system. Multiple carry options.

Precision-formed from durable .08 Kydex, the Flex Master Blaster is custom-built for your firearm and light combination, providing secure retention, full trigger guard protection, and a smooth, consistent draw. The flexible connection between the holster and magazine carrier allows the rig to move naturally with your body, increasing comfort and reducing printing during daily carry.

Whether you're carrying a Glock 19, Sig P365, Staccato, Smith & Wesson M&P, Springfield Prodigy, or another supported firearm, the Flex Master Blaster is built to perform when it matters most.

Why Choose the Flex Master Blaster?

Unlike traditional sidecar holsters that lock you into a single configuration, the Flex Master Blaster gives you the freedom to carry your way. Use the full sidecar setup when you want additional ammunition on hand, or quickly convert it into a standalone IWB holster for a slimmer profile.

This modular design makes it one of the most versatile appendix holsters available for concealed carry.
