GMI Holsters - Serpent AIWB Sidecar Kydex Holster

Our 'Serpent' series of holsters are designed to make appendix carry easier. They are engineered to be faster, more comfortable, more adjustable, and easier to use than the vast majority of other holsters on the market. If concealment is your objective, you wont find a better holster. 

This holster is perfect for anyone who has considered appendix carry but found it either uncomfortable or felt that it was obvious they were carrying a firearm. Since this holster has the ability to flex in the middle, its far more comfortable and concealable than other "sidecar" appendix carry holsters. Guaranteed, if worn correctly, nobody will know that you are armed and you can have a weapon at the ready in the blink of an eye!


Features of this holster:
  • Extremely durable and flexible neoprene connector holds the magazine carrier to the holster
  • Smooth textured .080 kydex gives a very unique look and reduces rubbing for a more comfortable fit (for other color options see the holster upgrades page above, we have a wide variety of other designs available)
  • Molded design latches onto gun with a desirable and reassuring 'click'
  • Features a "claw" to tuck the grip in closer to the body, greatly improving comfort and reducing "printing" through clothing
  • This holster can be made to fit a wide variety of handguns, check out the list above to see if we can make one for yours!
  • Fits 1.5" to 1.75" belts
  • Low cut for shorter draw length
  • Full sweat shield to assist re-holstering and keep clothes from snagging
  • Only the best hardware can be found on my holsters, the clips coming from Tacware and the Claw coming from RCS.
Thank you for considering this product from GMI Holsters "Safe. Simple. Strong."

    Perfect holster for TP9 Elite SC

    Posted by Royce Hamilton on Dec 22nd 2022

    Just received my serpent holster for my TP9 Elite SC. This product is perfect! High quality, great retention on pistol as well as clip holster. Definitely a well made product. I highly recommend. Sidecars are difficult to come by for TP9 Elite SC’s, I’m glad I found this one!

    Serpent Holster with Sidecar

    Posted by Joel G on Dec 21st 2021

    I have two Serpent AIWB holsters with sidecar mag carrier. I love them. They fit amazingly well and the retention on them is awesome. Super comfortable and I wear mine all day, everyday.

    I am very pleased with the service as well as the product. When I spoke with them they informed me that I put in the wrong gun type and I was able to get it corrected before they built the wrong one. Very pleased and would purchase product from them again.

    Incredible Customer Service

    Posted by Brian Messier on Oct 1st 2020

    After ordering the wrong holster, they allowed me to return it and added another model to their 'available list' to accommodate. After that, they sent another when the correct one was lost in shipping !! Extremely helpful and polite !! Top notch design and craftsmanship...and comfortable concealment of a full size double stack .45

    Holster fits great but the mag carrier is too big for my magazine making it pointless to buy the combo.
