Sleek, Modular Design
Kaizen redefines concealed carry holsters by reimagining traditional components and mounting methods that often result in bulky designs. Its streamlined approach delivers a noticeably slimmer profile, reduces spillover, and ensures discreet everyday carry without compromising functionality or speed.
Built for Maximum Adaptability
The Kaizen modular platform offers unparalleled customization to suit individual needs, incorporating industry-leading features, including:
-
LAS Stack It Wing System
Enhance your holster’s performance with the LAS Stack It Wing System, designed for ultimate versatility. With adjustable ramps of 7°, 11°, and 15°, and two height stackers, you can tailor the perfect grip tilt into your hip and stomach for ideal concealment and speed. -
LAS Stiff Hook Overhooks
The LAS Stiff Hook Overhooks deliver next-level durability and functionality to your Everyday Carry (EDC). Designed for a tough, secure fit, these overhooks keep your holster firmly in place and are compatible with belts like Kore, Nexbelt, and Blue Alpha (1.5”–1.75”). -
LAS Belt Mount Extensions
Easily optimize overhook placement to avoid pant buttons or belt loops, eliminating printing and enhancing stability. Effortlessly convert your Kaizen into an appendix rig by swapping the Kaizen Mount Extension and adding the Enso Mag Carrier. Kaizen is more than just a holster—it’s a platform that adapts to your needs.
This advanced adaptability empowers users to find their perfect balance between concealment, speed, and comfort.
Engineered for Professionals, Perfect for Everyone
Developed with insights from industry leaders, law enforcement, and military experts, the Kaizen Holster Series addresses common challenges such as bulky materials, grip printing, and flimsy overhooks—all without sacrificing comfort or concealment. This isn’t a social media gimmick; it’s a purpose-built solution for real-world performance.
Let customers speak for us
This is the best holster I have ever tried. I carry more and train more because of how comfortable this holster is.
Fits my pistol well and holds it very firmly. Holster is comfortable in both 9 o'clock (left handed), and 12 o'clock positions. Clips hold onto my belt so well they can be hard to take off, but I'd rather that than it be loose and interfere with my draw. All around perfect choice.
The Ronin-L is such an awesome conceal carry holster, it rides low in the pants making the weapon hardly noticeable on your shirt, especially for carrying a full size handgun it’s nice to not have to worry about the grip screaming hello through my shirt. By far the most comfortable light bearing holster I’ve used as well, and I love the adjustments for retention so you can dial in the holster just for you. Great, great product!
Australian customer. Great product, no rough edging and clean design. I received my Ronin quicker than expected for overseas shipping and a made to order unit. Very lightweight but sturdy, and the colour customisation is a cherry on top. Highly recommend
Big fan fits perfectly with the streamlight and i have no issues so far!
The holster is fantastic. The cut outs are great for conceal carry. You can easily get your hand around the gun without any issues.
Comfortable to carry and the retention is secure. Can't ask for much more from a holster.
I have several las concealment holsters they are probably my favorite carry holster. I took a chance with the saya for my new shadow systems fit great and my hope was with the pictures was I could use it inside or outside waistband it works for both just replacing the clips from one side to the other. Couldn’t be happier
Amazing customer service first off! I am a forever fan of Loaded And Safe(LAS) concealment. On top of that, these mag holders are adjustable...blows my freakin' mind!!!
I purchased this for my Shadow Systems MR920, and I couldn’t be happier!
I love this holster! It fits my gun so perfectly. It is so comfortable and I wear it everyday. This is my third one and love these holsters! Buy it and you won’t regret it.
No buyers remorse... a VERY comfortable holster, great for a daily driver... lots of piece of mind when drawing and reholstering... wish I'd pulled the trigger years ago...
I got this to replace my Tier 1. It still is a great holster but I decided not to run my Sig with the light anymore because it was too much bulk. The Shogun is very comfortable.
