Less Kydex.
More comfort.
Tantō is built for people who rotate their everyday carry but not their light.
Shark Fin Cut
Kydex removed at the outer edge of the light bezel and sanded smooth. No sharp corner pressing into your inner thigh.
Stack-It Wing System
The two stackers stack with the Stack-It Wing ramps to fine-tune how far the grip tucks into your body. Ride height is set by the Stiff Hook overhooks.
Retention screw
Adjust the screw on the back for a personal feel, with a positive “click” every time.
Stiff Hook overhooks
Tough, secure fit on 1.5″–1.75″ carry belts like Kore, Nexbelt and Blue Alpha.
How Tantō adjusts
Built around your light
Tantō is molded to your light. Every light below fits every model on the confirmed fitment list.
Pick your muzzle length
Open-ended. Pick Duty Cut, Flush, or Extended by where the muzzle sits versus the light bezel: recessed = Duty Cut, flush with the bezel = Flush, past the bezel = Extended. Most lights offer more than one length (PL350C: Flush only).

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.
absolutely love the holster. concealable and comfortable.
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!
