Classic Old Western Styles Mark IV Mark III COWS Belt Holster (Right-hand) with Magazine Holder, RH, 6-7/8″ Barrel
The Mark IV Mark III COWS belt side holster is an excellent product for right-handed Ruger owners who enjoy the classic Western style stitched leather holsters seen in cowboy movies for decades. The light brown leather is durable to withstand questionable weather conditions while keeping the six 7/8-inch barrel Mark III dry.
The belt loops accommodate belts up to two inches wide. Securely stitched at the back to maintain a regular fit on the waistband, this product makes a longer barreled weapon feel comfortable to wear. There is a leather strap that loops over the grip and snaps into place at the front. Further down the front is a magazine pouch with its own leather strap and a snap to avoid the magazine slipping out when bending forward.

- Clean, accurate white stitching throughout
- Right-handed use only
- Designed specifically for the Ruger Mark III and Mark IV models with a six 7/8-inch barrel
- Close fit for both gun and ammo
- Securing straps prevent Mark III, Mark IV or the cartridges slipping out
- Beautiful brown leather with excellent finish
- Fits comfortably on a 2-inch belt
- 30-day Money-back guarantee
- Won’t fit the Ruger Mark IV with mounted scope
- Too long for shorter barrel Mark III’s
- Overly tight fit initially. Benefits from leaving the Mark III and cartridges in place for a week
Choosing a Ruger Mark III Holster
There are different types of holsters for the Mark III mainly because of the varying barrel length. With the longer five or 6-inch barrel lengths, some holster styles simply wouldn’t suit it or permit a quick draw either. Thankfully, we’re blessed with a variety of styles and approaches that holster manufacturers have taken for the mix of Mark III models.
Here are a few things to think about when choosing a new holster for your Ruger Mark III.
Open Carry or Concealed Carry?
For the Mark III model with a 4½ or 4¾” barrel, there is the option for concealed carry (worn inside the waistband usually secured with a metal clip). For the longer barrel versions of the Mark III, open carry is going to be necessary. There are many more open carry models than concealed carry holsters available.
Can it hold a spare magazine?
Given that many of the holsters are designed for the longer barrel models, this allows enough space for the product to incorporate a magazine holder in many cases. Even with the more compact holsters for the sub-5-inch Mark III models, quite often there’s a slot to squeeze a cartridge into; it’s often easier to push the cartridge into than it is to extract it though.
Material & Feel
Most of the holsters are made from cow leather or another type that offers a comfortable wearing experience. With some of the small holster designs, they use Cordura ballistic Nylon, often with a barrier inside to ward off moisture reaching the weapon during long, hot days.
Nylon is good material for year-round use (especially in the heat), but leather is better in colder parts of the country.
The highest prices are consistently set for the leather holsters. The nylon-based ones are considerably cheaper. However, the longer barrel models are most often made from leather.
Is it compatible to hold other gun models too?
Unlike with some other weapon models, Ruger Mark holsters tend to be made specifically for certain Mark models. Quite often, several Mark models and variations are accommodated by a single holster. Generic holsters for Ruger Mark models are not commonplace.
Is there a way to adjust the fitting of the gun inside the holster?
Few holsters adapt to fit the weapon more securely because of the holster being made for the Mark III specifically. What is most important is to select a holster that’s suitable for the barrel length of your Mark III to avoid any issues.
Other Holsters for the Ruger Mark III
Pro-Tech produces a wide select of similar looking Cordura ballistic nylon holsters for many gun models. The situation is no different here. Their ambidextrous holster clips onto the waistband with a rugged clip that won’t let you down. It’s designed to hold the Mark III, plus one or two backup ammo clips too, without it moving around uncomfortably.
The material is a ballistic nylon on the exterior, followed by a vinyl barrier that soaks up moisture. Then an inner padding follows, with a soft nylon lining for the interior. There is a spring-loaded action thumb release. The stitching is made from bonded nylon and double-stitched at critical points.

2. Ace Case
The Ruger Mark III holster from Ace Case is a concealed carry product that is designed to be worn inside the waistband or on the belt. It has a universal design that works on either side of the body for left and right-handed people. The two-inch long clip is sturdy and unlikely to break.
The Cordura Nylon outer material, matched with a smoother faux leather, is a robust combination. Interior lining is soft and smooth for cleaner draws. There is a belt loop to support belts up the two inches wide to fit the holster outside the waistband for open carry options.

The Fobus Roto Evolution Series is a right-handed version of this holster that fits on the belt (there is a paddle version too). It is an injection-molded holster that doesn’t require oil or to breathe like leather holsters sometimes do. Maintaining the holster is a simple matter of washing it gently in the soapy water.
This holster uses passive retention because it lacks a pressure-button release mechanism or a retaining strap over the handle. The result is a faster draw than possible with a leather holster with a strap.
- Injection mold holster for the Mark III
- Slide the belt through holster’s belt loops to fit
- Non-fussy product for everyday use
- Faster action from unobstructed draw
- Adjust the fitting manually to secure the weapon more snuggly
- Easier to clean and maintain
- Wears better than leather over the years
- No nonsense holster with a professional appearance
- Will not accommodate a scope or other attachment
- No concealed carry
- No cartridge pouch for ammo
The Classic Old Western Styles Mark IV Mark III COWS Belt Holster is the one we preferred for a Mark III with a long barrel. It has quality leather and is ideal for different weather conditions. It is a right-handed model, so left-handed gun owners will need to choose a different holster.
The Pro-Tech Holster for a Ruger Model with 4 to 4 1/4 barrel is a good second choice for models of the Mark III sporting a much shorter barrel. It is very affordable and has an ambidextrous fit.
