1791 Size 2.1 Single Stack Magazine Holster

Product Description

The 1791 Size 2.1 Single Stack Magazine Holster is a belt-mounted carrier designed to hold one single-stack pistol magazine. This holster provides quick access to a spare magazine while keeping it secure during movement. It is built for everyday carry, range use, and competitive shooting where a reload needs to be within reach.

The Size 2.1 designation refers to 1791’s sizing system for magazine carriers. This model fits single-stack magazines, which are narrower than double-stack designs and commonly found in compact and subcompact carry pistols as well as full-size 1911-style handguns.

Magazine holsters serve a different role than gun holsters. They keep your spare ammunition organized, protected from lint and debris, and positioned consistently so your hand finds the magazine in the same place every time. Whether you carry concealed or open, a dedicated mag carrier frees up pocket space and speeds up your reload.

What Fits the Size 2.1 Magazine Holster

Single-stack magazines are slimmer than double-stack models because the cartridges sit in a single vertical column rather than staggered. Common examples include magazines for 1911 pistols in .45 ACP, many compact 9mm carry guns with six- to eight-round capacities, and older service pistols.

The Size 2.1 is narrower than 1791’s other magazine carriers and will not securely retain wider double-stack mags. If your magazine has two rows of visible cartridges when you look at the feed lips, you likely need a different size. Send us a message to confirm fitment for your specific magazine model.

How Magazine Holsters Mount and Carry

Most belt-mounted magazine carriers use a loop, clip, or paddle attachment that slides over your belt or inside your waistband. The magazine rides with the bullets facing forward or rearward depending on the design and your draw preference.

Positioning matters for reload speed. Many shooters place the magazine carrier on the support-hand side of the belt, just forward of the hip, so the drawing motion mirrors the path to the magazine well. Others prefer a strong-side placement behind the gun holster. Practice your draw from the location you choose so muscle memory builds consistency.

Magazine holsters also keep dirt and moisture away from the feed lips and follower. A clogged or damaged magazine is a common cause of malfunctions, and a covered carrier adds a layer of protection during outdoor shooting or daily carry.

Choosing Between Magazine Carriers

Magazine holsters differ in retention style, carry angle, and attachment method. Some use friction alone to hold the magazine, while others add a snap or adjustable tension screw. Open-top designs allow faster access but offer less retention during physical activity.

The 1791 Size 2.1 Single Stack Magazine Holster is purpose-built for narrower single-stack magazines. If you carry a double-stack pistol, look at 1791’s larger sizes or browse our full selection of holsters and magazine carriers to find the right fit.

Frequently Asked Questions

Q: Will the 1791 Size 2.1 magazine holster fit double-stack magazines?

A: No, the Size 2.1 is designed for single-stack magazines only. Double-stack magazines are wider and will not fit securely in this carrier. Single-stack magazines have cartridges arranged in one vertical column, while double-stack magazines stagger two rows. Confirm your magazine type before ordering.

Q: How do I know if my pistol uses a single-stack magazine?

A: Look at the top of the magazine where cartridges feed into the gun. If you see one cartridge directly behind another in a single line, it is a single-stack magazine. If cartridges alternate left and right in two columns, it is a double-stack magazine. Most 1911 pistols and many slim carry guns use single-stack magazines.

Q: Can I wear this magazine holster inside the waistband?

A: That depends on the attachment design, which is not specified for this model. Many magazine carriers work both outside and inside the waistband, but others are built for belt loops only. Send us a message to confirm the attachment method before ordering if inside-the-waistband carry is important to you.

Q: What is the difference between 1791 magazine holster sizes?

A: The size number reflects the width and capacity of the magazine the holster is designed to carry. Size 2.1 fits single-stack magazines, which are narrower than double-stack designs. Larger size numbers accommodate wider, higher-capacity magazines. Match the holster size to your magazine type for proper retention and fit.

Q: Does this magazine carrier work for rifle magazines?

A: No, the 1791 Size 2.1 Single Stack Magazine Holster is designed for pistol magazines. Rifle magazines are much longer and require a different carrier style. This holster is sized for handgun magazines only.
