Learn what the Tier 1 Concealed MSP holster is, how it works as a modular platform, and follow a step-by-step setup guide to get it ready for carry.
Quick answer
The MSP is a universal holster that locks onto your weapon light, not the pistol itself, so you can switch between compatible pistols without changing holsters. Setup is straightforward once you confirm your light model and choose the right mounting option.
Why the light matters more than the pistol
The MSP holster indexes on the weapon light instead of the firearm frame. That means the same holster can fit any pistol that runs a compatible light, as long as the light is mounted securely. This is a major advantage if you own multiple pistols that share a light platform, because you only need one holster for all of them.
Before you order, confirm which light you have. The MSP supports the SureFire X300, Streamlight TLR-1, and Modlite PL350. If your light isn't on that list, this holster won't fit correctly, and no amount of adjustment will make it safe.
What's included and what's not
The MSP is the firearm portion only. If you want a magazine carrier integrated into the same rig, you'll need to look at the MSP PRO Series or MSP PRO Series FLX. That distinction matters because it affects both the cost and the overall footprint of your carry setup.
Keep this in mind when you're planning your purchase: the base MSP gives you a dedicated holster, but it doesn't include a spare mag carrier. If you prefer an all-in-one solution, the PRO variants are designed for that.
How to set up your MSP holster
- Confirm your light model: Check the model number on your weapon light and verify it's a SureFire X300, Streamlight TLR-1, or Modlite PL350. If you're unsure, look up the light's product page or contact the manufacturer. Using an unsupported light is the most common mistake; double-check before you buy.
- Mount the light securely on your pistol: Attach the light to the rail according to the light manufacturer's instructions. Make sure it's snug and doesn't wobble; the holster's retention depends on a stable light. A loose light can cause the holster to fit poorly or release unexpectedly.
- Insert the pistol into the holster: With the muzzle pointed in a safe direction, slide the pistol with the mounted light into the holster until you hear or feel a positive click. The holster should lock onto the light, not the frame. If you don't feel a click, stop and re-check the light model; forcing it can damage the holster.
- Adjust retention and carry position: Use the provided screws to adjust retention to your preference, and set the belt attachment to your desired carry position (e.g., strong side, appendix). Test the draw and reholster to ensure smooth operation. Start with a moderate retention setting and tighten gradually to avoid over-tightening.
