At Tier 1 Concealed, innovation never stops. Even when a product is already proven in the real world, we believe there’s always room to refine, strengthen, and improve. That philosophy is exactly why we’re excited to introduce the updated MSP Pro Series holsters—our most refined universal, weapon-light–based holster system to date.
Designed in collaboration with Scott Jedlinski of Modern Samurai Project, the MSP lineup was created to solve a common problem in concealed carry: running multiple pistols with a single, high-quality holster—without sacrificing retention, safety, or comfort.
Below, we break down what the MSP holster is, what’s new in the latest update, and why it remains one of the most versatile holster systems on the market.
TL;DR
The updated MSP Pro Series holsters from Tier 1 Concealed are universal, weapon-light–based holsters designed to fit multiple pistols using the same light. The latest revision features redesigned light channels for stronger retention, simplified single-screw retention adjustment, improved trigger guard coverage, reinforced high-stress areas, a slimmer profile for better concealment, and easier reholstering. Available in MSP Pro (IWB), MSP FLX (IWB with attached mag carrier), and MSP OWB, the MSP lineup offers unmatched versatility without sacrificing safety, comfort, or performance.
What Is the MSP Holster?
The MSP (Modern Samurai Project) is a universal holster system built around your weapon light, not the firearm itself. Instead of buying a separate holster for every handgun, the MSP allows you to run nearly any pistol—as long as it’s equipped with the same supported weapon light.
This design makes the MSP ideal for:
-
Shooters who own multiple pistols
-
Training environments where guns are frequently swapped
-
Concealed carriers who want flexibility without compromise
Supported Weapon Lights
The MSP series is available for several of the most popular duty and concealed-carry weapon lights, including:
-
SureFire X300
-
Streamlight TLR-1
-
Modlite PL350 / PL350c
-
Cloud Defensive EPL
Mount your chosen light to almost any handgun, and the MSP holster will deliver a consistent, secure fit.

What’s New in the Updated MSP Holsters?
While the MSP holster isn’t new, this latest revision represents a major evolution in fit, function, and durability.
Redesigned Light Channels (Major Upgrade)
Each supported weapon light now features a completely redesigned light channel, resulting in:
-
More positive and consistent retention
-
A secure, audible click when holstering
-
A fit that feels closer to a gun-specific holster—despite being universal
Whether you’re running a Glock, Staccato, Walther PDP, 2011, or Zev OZ9, the updated MSP delivers a remarkably consistent draw and lockup.
Adjustable Retention—Simplified
Retention is highly personal, and we’ve made it easier than ever to dial in.
-
One dedicated retention screw now controls light retention
-
Concealment claw screws no longer affect holster retention
-
Hard spacers replace soft spacers for consistent pressure and reliability
This streamlined setup eliminates confusion and ensures your holster stays properly tuned.
Improved Safety and Durability
Enhanced Trigger Guard Coverage
The updated MSP features a redesigned upper profile that fully covers the trigger guard, helping prevent:
-
Foreign objects from entering the holster
-
Accidental trigger engagement while holstered
Safety is non-negotiable when it comes to concealed carry, and this update reflects that priority.
Reinforced High-Stress Areas
We added gusseting and reinforcement in areas that experience the most pressure—especially around the concealment claw. This improves long-term durability, even when the belt is worn tight for maximum concealment.
Better Concealment, Slimmer Profile
Several refinements were made to enhance comfort and concealment:
-
Reconfigured belt clip placement for a slimmer front-to-back profile
-
Less aggressive clip angles that sit closer to the holster body
-
Reduced bulk without sacrificing stability
These changes result in a holster that’s easier to conceal and more comfortable for all-day wear.
Concealment Claw Improvements
The concealment claw has been repositioned closer to the plane of the primary belt clip, giving it more authority against the belt and waistband. This:
-
Pushes the grip into the body more effectively
-
Reduces printing
-
Maintains full adjustability via removable claw stacks
Whether you prefer aggressive concealment or a softer setup, the MSP adapts to you.
Faster, Easier Reholstering
The holster mouth has been widened near the logo area to allow:
-
Easier alignment of the muzzle and weapon light
-
Faster, safer reholstering
-
Less fumbling under stress or during training
Smooth, consistent reholstering matters—especially for concealed carriers who train regularly.
Universal Fit That Actually Feels Universal
During testing, we ran a wide range of pistols through the updated MSP, including:
- Walther PDP
- Atlas Double Stack 1911's
- Staccato P
- Zev OZ9
- Sig Sauer P320
- Glock 17 Gen 5
- Smith & Wesson M&P
- many, many more
Despite differences in frame size and grip height, each firearm exhibited minimal movement and excellent retention—proof that universal doesn’t have to mean generic.

Frequently Asked Questions (FAQ)
Is the MSP holster truly universal?
The MSP is universal based on the weapon light, not the firearm. As long as your pistol is equipped with a supported light (such as the SureFire X300 or Streamlight TLR-1), it will fit securely in the corresponding MSP holster.
Does the MSP provide adequate retention for concealed carry?
Yes. The redesigned light channels create a very positive lockup with minimal movement. Retention is user-adjustable via a single screw, allowing you to fine-tune the draw to your preference.
Is the MSP safe for appendix carry?
Absolutely. The updated MSP features improved trigger guard coverage to help prevent foreign objects from contacting the trigger, making it a safe and reliable option for appendix inside-the-waistband (AIWB) carry when used properly.
What’s the difference between MSP Pro and MSP Flex?
The MSP Pro includes a standalone holster and a separate, unattached magazine carrier. The MSP FLX connects the spare magazine carrier to the holster using shock cord, similar to the Axis Elite, for an integrated appendix carry setup.
Can I use the MSP OWB for duty or range use?
Yes. The MSP OWB is designed for outside-the-waistband carry and is compatible with battle belts and other mounting solutions, making it ideal for range training, classes, and overt carry.
Will different pistols sit at different heights in the holster?
Slightly, yes. Grip height can vary depending on how the weapon light interfaces with each firearm, but retention and security remain consistent across supported pistols.
Do I need to adjust multiple screws to change retention?
No. On the updated MSP holsters, only one screw controls retention. The other screws are dedicated to securing and adjusting the concealment claw.
Are the updated MSP holsters replacing the older versions?
Yes. The updated MSP Pro, MSP FLX, and MSP OWB holsters have replaced the previous versions and are now the standard offerings on the Tier 1 Concealed website.
