Subject Matter Expert Review

Been rocking this Red 1 USA ShivWorks MkII holster for a bit and am happy with it. Things I like- g17 length (rides where it needs to even if carrying g19 or 26.) Double fixed loops- for me personally, I prefer fixed loops, sized to the belt I'm wearing, for maximum security. If they're narrow, there should be two. Performance trumps convenience here. This ensures the gun's grip stays in a consistent, predictable position and one loop is also a backup in case the other comes undone. Two positions to choose from for ride height, the holster is blocked out to allow different RDS, slide stops, sights to fit. The built in wedge near the muzzle tucks the grip tighter against your gut. The ledge on the sweatguard can be used to kick the holster off the gun with one hand/your thumb if you're retrieving the gun and holster from a bag, table, drawer etc. Very clean work and design overall. Add this one to your list of AIWB holsters worth trying out.

    I had the opportunity to demo this holster at a Shivworks ECQC course and I am very Impressed. The closed loops are solid, easy to get on your belt and give you a little “wiggle” room. The holster is thin, light, durable and provides excellent concealment. Great product!

    This is my third holster i have ordered from Red 1. Great quality and very concealable. I have tried others but I think these are the best.

  3. Frank J.

    Probably the most comfortable and concealing holster I have yet to wear. Will be purchasing more for my other guns.

    This is one of the very few holsters my company would recommend to our students because it covers all the bases: properly covers the trigger guard, positive passive retention, belt loops that won’t slip off, adjustable wing, G17 length with open muzzle, works with suppressor height sights and MRDS, the list goes on. Very well thought out.

  5. John S.

    I’m very surprised with my shivworks holster cause it works and it work very well. I been wearing my new holster almost everyday and I love it. Brilliant stuff!

    Very impressed with this holster. Comfortable, obviously robust, great retention, and plenty fast from which to draw. My list of favorite holster makers just went from two to three.
