The T.REX Sidecar Holster is a modular inside‑the‑waistband system engineered for appendix carry with an emphasis on adaptability, stability, and concealed performance. Constructed from precision‑formed 0.093‑inch Kydex, the holster body and attachments are formed as single pieces for durability and consistent retention. The integrated Spine System allows the platform to flex with body movement while maintaining alignment for a smooth, repeatable draw. Compatibility supports slide‑mounted optics and suppressor‑height sights up to approximately 0.5 inches, making it suitable for modern handgun setups.

The system includes a removable Sidecar Wing attachment, adjustable claw, and mounting hardware, allowing users to configure the holster for additional gear such as a magazine or medical equipment. Attachment positioning supports adjustable ride height, and retention can be tuned based on preference. Tuckable clips fit belts up to 1.75 inches and provide secure, stable carry. Designed for both standalone and modular use, the Sidecar delivers a versatile concealed carry platform that balances customization, durability, and comfort.
