Garage Sale One Shot Single Mag Carrier Review: Double Stack 9/40

If you carry a double stack 9mm or .40 caliber pistol, you know that a spare magazine is non-negotiable. But not all mag carriers are created equal. Some are bulky, some are flimsy, and some just don't hold up to daily use. That's where the Garage Sale One Shot comes in. This single mag carrier promises to be a simple, durable, and affordable solution for carrying an extra mag. In this review, we'll put it to the test and see if it lives up to the hype.

The One Shot is part of Garage Sale's lineup of no-nonsense gear. It's designed for those who want a reliable mag carrier without breaking the bank. We've tested it with a variety of double stack mags, including Glock 17 and Sig Sauer P320 mags, to see how it performs in real-world conditions. Read on for our full assessment.

Design and Build Quality

The One Shot mag carrier features a minimalist design that focuses on function over form. It's made from a rigid polymer that feels sturdy in hand. The carrier is open-top, allowing for quick and easy access to your magazine. The retention is adjustable via a tension screw, which is a nice touch at this price point. The clip is a standard belt clip that fits belts up to 1.75 inches wide, making it versatile for most carry setups.

One of the standout features is the construction. The polymer is thick and doesn't flex excessively, which means it will hold its shape over time. The edges are smooth, so it won't snag on clothing or cause discomfort. The clip is securely attached and doesn't wobble, which is a common issue with cheaper carriers. Overall, the build quality is impressive for the price.

• Rigid polymer construction for durability
• Adjustable retention via tension screw
• Fits belts up to 1.75 inches
• Open-top design for quick access

Fit and Compatibility with Double Stack Mags

The One Shot is specifically designed for double stack magazines, which is great news for those carrying 9mm or .40 caliber pistols. We tested it with a Glock 17 mag (17 rounds) and a Sig P320 mag (17 rounds), both of which fit snugly. The carrier held the mags securely without any rattling, and the adjustable tension allowed us to fine-tune the draw. The mag sits deep enough to be secure but not so deep that it's hard to grip.

For those carrying a .40 caliber, the carrier also works well. The dimensions are similar to 9mm double stacks, so the fit is just as good. The open-top design means that even mags with base plates that are slightly larger will still fit without issue. However, if you have a mag with an extended base plate, you might find that it sits a bit higher, which is actually beneficial for a quicker draw.

• Compatible with Glock, Sig, and most double stack 9mm/.40 mags
• Secure fit with no wobble
• Adjustable tension for preferred draw

Comfort and Concealability

Comfort is key when you're carrying a spare mag all day. The One Shot is surprisingly comfortable, even when worn for extended periods. The carrier sits close to the body, which helps with concealment, and the clip is low-profile enough to be hidden under a shirt. The polymer doesn't dig into your side, and the smooth edges prevent any chafing.

The carrier works well for both appendix and strong-side carry. We tested it at the 3 o'clock position and found that it didn't print noticeably under a t-shirt. The minimalist design means it takes up minimal space on your belt, which is a plus if you already have a holster and other gear. If you're looking for a mag carrier that you'll forget you're wearing, the One Shot is a solid choice.

• Low-profile design for concealment
• Comfortable for all-day wear
• Works for appendix or strong-side carry

Performance in the Field

We put the One Shot through its paces with live-fire drills and dry practice. The carrier held up well, with no signs of wear or loosening. The retention stayed consistent, and the mag was easy to draw every time. We also tested it in various positions, including bending and running, and the mag stayed in place. The carrier doesn't shift on the belt, which is crucial for a smooth reload.

One thing to note is that the tension screw is the only adjustment point. If you prefer a very tight retention, you'll need to crank it down, but that might make the draw a bit harder. We found the sweet spot after a few adjustments, and it worked perfectly. The open-top design also makes it easy to re-index the mag after a reload, which is a big plus.

• Holds up to rigorous use
• Consistent retention
• Easy re-indexing

Comparison with Other Mag Carriers

In the market, there are many single mag carriers, but the One Shot stands out for its affordability and quality. Compared to similar products from other brands, the One Shot offers a better price-to-performance ratio. It lacks some of the advanced features like adjustable cant or modular attachments, but for most users, that's not a dealbreaker. It's a straightforward, reliable carrier that does its job well.

If you're considering other options in the Garage Sale lineup, you might also look at the GTTK Sidekick, which is a different style of carrier. However, for a simple single mag carrier, the One Shot is hard to beat. It's also worth noting that the One Shot is compatible with the Fast Strap system, which allows for different mounting options, adding to its versatility.

• Affordable price point
• Simple and effective design
• Compatible with Fast Strap for alternate mounting

The Garage Sale One Shot is a solid choice for anyone in need of a reliable single mag carrier for double stack 9mm or .40 caliber mags. It's durable, comfortable, and affordable, making it a great addition to your EDC setup. If you're in the market for a mag carrier that won't let you down, give the One Shot a try.
