Elevate Your Everyday Carry
The Kaizen Holster Series is a modular and innovative platform designed for professionals and enthusiasts who demand superior performance and adaptability. Inspired by the Japanese philosophy of continuous improvement within a group of shared interests, Kaizen embodies the relentless pursuit of evolving with you on your journey to excellence.
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.
I got the Kaizen for my Staccato 24 C and love it. The holster has great retention and fits the gun like a glove. The belt loops are well made and work good to keep the holster in place. I will definitely be recommending LAS holsters.
More belt attachment options during initial order would have been nice. Otherwise, great holster!
Perfect holster for my G34 Gen5 mos!
Been carrying the Staccato CS in this holster since it arrived. Awesome fit. Went to the range and did some drills. Pistol draws clean. Reholsters easy. Strongly recommend.
As the owner of 10 other holsters, I can say with certainty that this one is my favorite. It fits the gun very well, it fits me very well. It's well designed and you can tell that a lot of thought went into it. I love the adjustability, and the clips are very chonky.
This is my new go to holster company for IWB. The price is very fair for what you get.
Let customers speak for us
As a daily concealed carrier and a firearm instructor, I’m always on the lookout for top-tier gear that meets both personal and professional standards. I already own two LAS Shogun holsters, so my expectations were high when I got my hands on their latest offering: the AIWB Kaizen.
Let me tell you, it didn’t just meet expectations—it surpassed them. The AIWB Kaizen stands out with its precision craftsmanship, thoughtful design, and impressive comfort. Whether you’re an experienced carrier or just starting out, this holster delivers on every front.
What sets LAS apart—and why I confidently recommend them to my students—is their commitment to quality. Their Kydex holsters are second to none, providing the perfect balance of durability, retention, and comfort. The AIWB Kaizen is no exception. It’s clear that LAS continues to innovate and refine their products, staying ahead of the curve in the industry.
If you’re searching for a reliable, well-crafted holster, LAS should be your go-to. The AIWB Kaizen proves once again why they’re at the top of the list for Kydex holsters. Highly recommended!

Wanted to give this a try as I like the idea of modularity. Once I messed around with different adjustments, I can conceal my full size Echelon with ease! Build quality is fantastic as well.
Most comfortable holster I’ve had. Appendix or 3-4 o’clock doesn’t matter. Completely forget you have it on
This is the best holster I have ever used. Great retention, stays exactly where you put on your belt, and the kit for adjusting the claw is exactly what I needed. 10/10 would recommend.
I’ve got another LAS holster and their quality is top notch. The ability to add a light from many options is fantastic as well. They’ve got my life long business for sure!
The holster came in great shape! I love the designs options that LAS offers. I do suggest that you have a firm duty belt when buying one of these holsters. It’s an amazing product and worth the money!
Really impressed with this holster. Seems to be well made. No rough edges. Retention is perfect right out of the package. Shipping took exactly how long that was specified on the website. Overall positive experience. 👍
My EDC is a full-size 1911 with a Surefire X300. This is my first time with Appendix Carry. I watched more videos than I care to admit on this carry position, and the Saya came highly recommended. It makes carrying a full-size weapon extremely comfortable and extremely fast to access. The holster is everything that I expected. I did opt for the discrete carry clips. The stability and the adjustability of the clips are amazing. LAS customer service went above and beyond to make sure that I chose the correct size holster for my setup. They are a top-tier company with a top-tier product.
This holster is excellent. I have this design for 3 different sized hand guns. All excellent. I have been using them for years with very litte if any signs of wear. They have held up great. Highly recommend
Great holster for my Glock 43X when I need a smaller setup, really strong and durable. Great color options to make it your own.
Great holster for G48 MOS w/TLR7 sub. The extended mag option fits my Shield S15 +5,+2 and 15 round mags perfectly, which to me is pretty insane really. The retention on the pistol and mag sidecar were exceptional out of the gate. It’s comfortable all day standing and sitting, which was super important for me. Only downside was I ordered it with the standard LAS overhooks (they’re great). I just wish I had ordered with the stiff overhooks for even more adjustability. LAS really nailed it on this one and I couldn’t be more happy with my decision to give them a shot!
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!
