Galco Combat Master 2.0 Now Fits the Glock 21, Optic or Not
Galco has added the Glock 21 to the fit list for its Combat Master 2.0, the updated version of the company's long-running pancake-style outside-the-waistband holster. The new fit works with or without a carry optic, which matters for anyone running a red dot on a full-size .45 ACP. Galco announced the addition in a release and lists the Glock 21 fit as available now. The company did not publish a price and offered no color or hand options at launch. The holster uses an optic cutaway, so one leather design serves both iron-sighted and optics-equipped pistols. For a gun owner who carries a big .45 and wants a slide-mounted dot, this changes the shopping list.
Key Details
Galco built the Combat Master 2.0 as an optic-cut leather holster. The body cutaway clears most carry-style optics while still accommodating pistols with iron sights. Galco says the cutaway lets the pistol clear the leather faster, producing a quicker and smoother draw, and it points to shorter-waisted shooters as a group that benefits most. Each holster is hand-molded to a specific handgun, which Galco credits for both retention and fit. Construction uses premium steerhide with double-stitched seams.
- Model: Combat Master 2.0

- Style: Traditional high-riding pancake, outside the waistband

The twin belt slots draw the pistol tight against the body for concealment and spread the weight of the gun across the belt. The raised sweat guard does double duty, separating the steel from skin and keeping moisture off the frame.
Background
Pancake holsters rose to popularity because they sit flat against the torso, which reduces printing under a shirt. The design relies on a belt-mounted body that hugs the pistol. Galco has built holsters in this style for decades and has become one of the better-known American names in leather carry gear. The Combat Master line sits among the company's core offerings.
Red dot optics changed holster design. As more manufacturers offered optic-ready pistols, holster makers began cutting leather to clear mounted optics instead of forcing owners to choose between a dot and a proper holster. Glock has offered optic-ready versions of several models, which pushed demand for compatible holsters across its lineup. The Glock 21 is a full-size .45 ACP pistol that has long served duty, competition, and home defense roles. Adding it to Galco's fit list follows that trend. Each optic model still needs its own cutaway, so fit depends on the specific optic and pistol combination.
Why It Matters for Gun Owners
The Glock 21 owner who runs a dot gets a real option here. Before this addition, a Glock 21 with an optic often meant a holster from a different maker or a custom order. Now a Galco buyer can pick a traditional pancake with an optic cut and avoid switching brands for a dot-equipped carry rig.
Check the fit before buying. Galco says the holster clears most carry-style optics, but "most" is not "all." Measure the height of your optic and its housing, then compare it to the cutaway on the holster. Bring the pistol and optic to a shop if you can, and dry-fit the rig. Check retention by drawing and then bending forward and turning at the waist. A pancake that shifts or tilts under those movements needs a different belt setup or a different holster.
Belt width matters too. The twin slots accept belts up to 1 3/4-inch wide. Many dress belts are narrower, so a thin belt may sag and let the holster droop. A proper gunbelt with stiffened leather keeps the rig stable. Owners who carry in places that require a specific holster style or retention level should confirm local requirements before buying.
DownRange Analysis
Bruen does not touch holsters directly. The 2022 decision confirmed that the Second Amendment protects carrying a handgun in public for self-defense, and that protection only works if a gun owner can carry the firearm safely and comfortably. Holsters are the practical hardware that makes that right usable. A holster that clears a dot and keeps the pistol secure supports lawful carry in a real way, even though no court will ever rule on it.
Market-wise, this is a sign that holster makers are catching up to optic-equipped pistols. Expect other makers to follow with similar cutaways. Galco has not published a price, so watch for that number before judging value. If you run a Glock 21 with an optic, measure your setup now, confirm the fit with the company or a dealer, and test retention before you carry. If you carry a Glock 21 with iron sights, this release changes nothing for you except that you now have one more pancake option.
