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, 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.
