The MAINSTAY™ Inside the Waistband Holster provides immediate access to your firearm and allows for multiple styles of carry. The silicone-coated outer shell offers unbeatable slip resistance - keeping the holster firmly in place as you draw. This ambidextrous IWB holster is constructed with superior materials and will not flake or disintegrate over time with use. The Mainstay holster's soft interior lining helps to protect the weapon, and the water-resistant materials will not absorb moisture. The Mainstay holster is made in the USA and offers a lifetime guarantee. The holster is ambidextrous and is offered in a variety of sizes to fit popular handguns. See holster size listing below.

  • Non-slip outer shell keeps this holster in place as you draw
  • Light weight, water resistant materials perform better than leather
  • Soft interior lining protects weapon and eases draw and re-holstering
  • Low profile design supports inside-the-waistband or pocket carry
  • Proudly made in the USA
