4BROS Icarus Precision P365 DadBod Appendix Rig – IWB Sidecar Holster for Bigger Builds (and skinny people too)
Designed for comfort, built for concealment. The 4BROS Icarus Precision P365 DadBod Appendix Rig is an inside-the-waistband (IWB) sidecar-style holster system, purpose-built for individuals with larger body types who want to carry Sig P365 pistols equipped with an Icarus Precision grip and magazines in a sidecar-style appendix rig—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.
