Description

4BROS Sig Sauer P365 Series DadBod Appendix Rig – IWB Sidecar Holster

Designed for comfort, built for concealment. The 4BROS DadBod Appendix Rig is a premium Inside Waistband (IWB) sidecar holster system engineered specifically for the Sig Sauer P365 series of pistols, including the P365XL, P365-XMACRO, P365-FUSE, P365-FUSE COMP and P365-AXG Legion models.

Not sure which AXG Legion generation you have? Use our P365 AXG Legion fitment guide for Gen 1 vs Gen 2 models.

If you have a P365 or P365X, select the P365XL holster. You will have extra room at the muzzle, but that will aid in concealment (like a sailboat keel).

This appendix carry holster supports both P365 pistol-only and light-bearing configurations, delivering secure retention, adjustability, and all-day comfort for concealed carry.

Key Features of This Sig P365 IWB Holster

  • Precision Fit for P365 Series: Custom-molded for secure retention across P365 variants and compatible weapon-mounted lights.
  • Adjustable Sidecar Spacing: Fine-tune the distance between holster and magazine carrier for improved comfort and concealment.
  • Tegris Appendix Adapter Plate: Durable, flexible platform with “D-cut” relief to reduce pressure points during appendix carry.
  • Light-Bearing Retention System: Light-compatible models retain securely on the weapon light for consistent draw performance.
  • Adjustable Cant & Ride Height: Customize carry angle and ride depth for optimal draw and concealment.
  • Designed for All Body Types: Built for larger builds while remaining fully adjustable for slimmer users.

Comfort & Concealed Carry Performance

This appendix IWB holster is designed to reduce discomfort commonly associated with traditional sidecar holsters. The adjustable spacing and flexible Tegris system allow the holster to conform naturally to your body, improving concealment and long-term wearability.

4Bros Holster Wedge— Designed to improve concealment and comfort by helping angle the firearm grip closer to the body while reducing pressure points during IWB carry.

For long-term reliability, apply a removable thread locker to all hardware after initial setup to help prevent loosening during regular use.

See our Apply Thread Locker to Your Holster video for a quick application guide.
