4BROS Fat Guy’s Appendix Rig – IWB Sidecar Holster for Bigger Builds (and skinny people too) Designed for comfort, built for concealment. The 4BROS Fat Guy’s Appendix Rig is an inside-the-waistband (IWB) sidecar-style holster system, purpose-built for individuals with larger body types—because not everyone has a six-pack, and that's okay. But don’t worry—skinny guys can use it too. The adjustable width makes it ideal for all body types. This custom appendix rig features adjustable spacing between the holster and magazine carrier, using our unique Tegris Appendix Adapter Plate with a relief “D-cut” that adds flexibility and reduces pressure points. Whether you are built like a linebacker or rocking that dad bod, this rig provides the space you need to carry comfortably and conceal effectively. Product Features: Built for Bigger Bodies – Extra spacing between the holster and mag carrier improves fit and comfort for larger builds. Adjustable Width – Customize the distance between the holster and mag carrier to suit your body type. Tegris Appendix Adapter Plate – Durable, flexible, and designed to reduce hot spots and increase comfort in the appendix position. Retention on the Light – Light bearing versions lock in on your weapon-mounted light for a secure fit and consistent draw. Adjustable Cant & Ride Height – Tailor the angle and position for both the holster and the mag carrier to your exact preference. Available in Limited-Release Colors – Ask us about custom options—we’re easy to talk into cool ideas.
