Overview

Firearm enthusiasts who rotate between several handguns often face the inconvenience of maintaining multiple holsters. The Tier 1 Concealed MSP (Modular Sportsman’s Pack) holster is designed to solve that problem by accommodating a wide range of pistol sizes and configurations in a single platform.

Pros

• Universal fit: Works with full-size, long-slide, compensated, and double-stack 1911/2011 models by securing pressure on the weapon-mounted light rather than the frame.
• Versatile carry options: Available in appendix inside-the-waistband (AIWB) with optional, removable magazine caddy, and outside-the-waistband (OWB) configurations compatible with most quick-detach systems.
• Daily-use durability: The reviewer reports carrying the holster daily on and off the range with no reported issues over extended ownership.

Cons

• Limited compatibility: Excludes very large or unconventional handguns such as the Desert Eagle .50 or Chiappa Rhino 60DS.
• Requires a weapon-mounted light for retention, which may not suit users who prefer light-less setups.

Specs

• Models: AIWB (with or without mag caddy) and OWB belt-mount versions.
• Retention method: Light-bearing pressure fit.
• Intended use: Everyday concealed or range carry for multiple pistol platforms.

“I don’t want to have a different holster for all of these things,” the reviewer states. “So, for that reason, I run a Tier 1 MSP holster.” He adds that the design “will carry everything you have in your collection, unless you’ve got like the Deagle 50 or the Chiappa Rhino 60DS.”
