Spare Mags for When you Need it Most

When people think about their concealed carry setup, they usually go for a nice holster and maybe some upgrades like a light or an optic. But carrying an extra magazine is one of the most practical and overlooked upgrades to any concealed carry setup. While most concealed carriers focus on firearm selection and holster choice, a quality extra magazine carrier plays a critical role in reliability, preparedness, and real-world defensive performance.

If you’re serious about everyday carry, pairing your handgun with a well-designed dual magazine carrier—like The Flex IWB/OWB Universal Flex Dual Mag Carrier —is a smart and responsible choice.

Our team at Bucks Holsters is going to break it down.

The Real Reason You Should Carry Extra Magazines

More ammunition is only part of the equation. In real-world defensive situations, magazine-related malfunctions are among the most common handgun failures. Feed issues, damaged lips, worn springs, or debris can instantly take your firearm out of action, which can mean life or death for you and the people around you

A spare magazine allows you to:

• Instantly resolve magazine-related malfunctions
• Restore function faster than clearing complex stoppages
• Maintain defensive capability under stress

Carrying extra magazines isn’t excessive—it’s redundancy.

Why a Dual Mag Carrier Makes Sense

Single magazine carriers are effective, but dual magazine carriers offer additional advantages:

• Increased capacity without extra bulk
• Balanced weight distribution across the belt
• Fewer separate pieces of gear to manage
• Faster access to a second reload if needed

The challenge has always been comfort—until flexible designs changed the game.

The Flex IWB/OWB Mag Carrier: Comfort Meets Capability

The The Flex Universal Dual Mag Carrier from Bucks Holsters takes their proven universal magazine carrier and enhances it with a dual-flex design, connecting two carriers with a durable flex joint that moves naturally with your body.

This flexible connection dramatically improves comfort whether you’re:

• Standing or sitting
• Driving for long periods
• Carrying appendix, strong side, or OWB

Unlike rigid dual carriers, The Flex adapts to your movement instead of fighting it.

IWB or OWB Carry — Fully Ambidextrous

Versatility is a major advantage of The Flex mag carrier. It is designed to work for concaled carriers who enjoy inside-the-waistband (IWB) or even people who enjoy carrying outside-the-waistband (OWB) and is fully ambidextrous, making it ideal for both right- and left-handed shooters.

This allows you to:

• Adjust your carry style seasonally
• Match your mag carrier to multiple holster setups
• Train and carry with the same equipment

Premium Kydex Construction You Can Trust

Each Flex mag carrier is handmade in the USA at Bucks Holsters’ Cape Coral factory and vacuum-formed from .080 Kydex using precision computer-designed molds.

Key construction details include:

• Smooth, beveled, and polished edges for all-day comfort
• Durable material that holds shape over time
• A slim profile for excellent concealment

This level of craftsmanship ensures reliability you can depend on daily.

Fully Adjustable Retention for Each Magazine

The Flex features independent MRDs (Multi-Retention Devices) for each magazine, allowing you to fine-tune retention on both carriers separately. This ensures:

• Secure carry without excessive tension
• Consistent draw pressure
• Compatibility across different magazine types

An included 1/8-inch Allen key makes adjustments quick and simple.

Attachment Options for Every Carry Style

One of the biggest advantages of the Flex mag carrier is its wide range of attachment options, allowing you to tailor it to your exact carry needs:

• 1.5" or 1.75" FOMI Clips – Easy on/off belt carry
• Bucks Holsters H-A-R-T Clip – Metal, ultra-secure, works with or without a belt
• DCC Monoblock – Industry-standard steel clip with exceptional retention
• Soft Loops – Maximum security for duty or extended wear
• UltiClip / UltiTuck – Ideal for beltless carry like gym shorts or sweatpants

Whether you’re dressing casually or carrying more traditionally, the Flex adapts.

The Flex is available in multiple magazine configurations to fit most popular concealed carry pistols:

Final Thoughts: A Smart Upgrade for Serious Concealed Carriers
