The Grayguns Custom Appendix Inside-the-Waistband Holster is a collaboration between PHLster Holster, Henry Holsters and our own law enforcement director, Mike Grasso (LAPD).

The holster utilizes a PHLster wedge to orientate the grip of the weapon closer to your body which reduces printing and its slightly longer length reduces the chance of the holster flipping over your belt. All of our holsters are designed to be used with RDS Optics and most manual safeties.

Designed with two soft loops that can removed or reoriented if needed. Molded in a Grayguns gray finish and hot stamped with our logo!

Fit Guide

Available for the SIG Sauer P365 (also fits XL and all P365 with/without manual safety), P320, P220, P226, P229 & P228.

Our P320 holster fits all variations of the P320, including the X-Five and those chambered in .45 ACP. They also fit both versions of the takedown lever and will fit models with and without the manual safety.

    The perfect appendix holster

    nick.dunford (verified owner)

    I’ve been on the hunt for this holster for a while and I am not disappointed. It has everything you need for a perfect appendix carry. The built-in wedge and “pseudo-wing” do a wonderful job of getting the gun nice and secure against your body, yet somehow it is also comfortable. The kydex is beautifully crafted and the “click” when holstering is secure and comforting. I love the loops as it is much more secure than my previous clip holster. When you are moving and bending over a lot at work it isn’t impossible for the big plastic clips to work their way off a belt.

    I just can’t say enough good things about this holster and I am honestly elated that someone went into my brain and designed my perfect holster.

    Ordered for my 320 X-Carry. The holster is built for all versions of the 320 so for the X-Carry there is about an inch of space between the end of the barrel and end of the holster from the inside. Very well made and easy to draw from. Shipping was extremely fast and there was no issues.
    Edit: upgraded to 5 stars after carrying for a while, absolutely perfect holster.

    Great Holster!

    I’ve been rocking this holster for my SIG P320F for the past three months. For such a large handgun, I have decided to use the holster as a conventional inside-the-waistband holster at the 4 o’clock position by adjusting the belt loops to allow for better concealability with a forward cant.

    Although I initially found the teardrop wedge and TuckStrut wing uncomfortable as they applied pressure to my hip, I eventually got used to it and found both features useful in minimizing printing as they keep the frame of the P320 close to the body.

    I found drawing and reholstering of my P320 into this holster to be positive. I would describe the “kydex click” as being very crisp.

    I am very impressed with the level of attention and detail that went into this holster, and am considering getting another; after all, “two is one, and one is none…”

    The best appendix holster period

    spahceidde (verified owner)

    This holster not only makes the gun disappear but it sits perfectly against your body. I can wear this thing all day and not really notice it. If you carry appendix or hell even if you don’t this is a great holster.
