The decision to carry a spare magazine is often debated among concealed carriers. Statistically, the odds of needing additional ammunition in a defensive encounter are low. Most documented shootings occur at close range, frequently within three yards, and involve only a few rounds fired. Yet focusing solely on probability misses the larger point: preparedness. Just as carrying a firearm is not about likelihood but about readiness for a life-threatening event, carrying a spare magazine reflects a mindset of planning for contingencies rather than relying on statistics. Sound judgment in personal defense requires weighing both probability and possibility.
Carrying a spare magazine isn’t just about increasing the number of available rounds. Magazines are mechanical devices, and like any mechanical component, they can fail. A damaged or malfunctioning magazine can cause feed failures, jams, or stoppages that render a firearm temporarily inoperable. In such a scenario, the fastest and most effective solution is often to eject the faulty magazine and insert a fresh one. Seconds matter in a defensive encounter, and the ability to quickly get back into the fight can be critical. For this reason, I make it a personal habit to carry at least one spare magazine, more if circumstances warrant.
Pocket Mag Carry
Pocket carry remains a popular method for stowing a spare magazine. However, simply dropping a magazine into your pocket is far from ideal. It can shift, snag, or become difficult to access quickly. Fortunately, specialized carriers exist to solve this problem, offering secure retention and rapid accessibility.
One standout innovation is the Ulticlip® ENDUO™, developed and patented by UltiClip—Ultimate Carry Solutions. The ENDUO is the world’s first pocket-carry solution that attaches directly to the magazine, eliminating the need for extra gear. Its name, derived from the Ancient Greek word meaning “to sink into clothing,” reflects its discreet, low-profile design. The ENDUO allows for clean, secure carry while enabling fast reloads when seconds count.

The Ulticlip ENDUO
The Ulticlip ENDUO is truly revolutionary. It features a discreet, retractable clip that tucks flush against the magazine base when drawn, reducing the chance of snags and enabling smooth reloads. It also doubles as a bumper pad, ensuring a secure magazine seat—particularly useful for flush-fit designs.
Constructed from high-strength polymer and paired with a low-profile, black-oxide finished stainless steel clip, the ENDUO is engineered for durability without adding bulk. Installation is simple, requiring no tools or permanent modifications. Its ambidextrous design allows magazines to be staged with rounds facing left or right, depending on user preference. Once installed, the ENDUO positions the magazine deep in the pocket, minimizing printing while maximizing accessibility. Its exposed profile is so discreet that it’s barely noticeable.
One limitation of the ENDUO design is that it leaves the magazine feed lips exposed. This can allow pocket lint or other debris to accumulate, potentially interfering with the magazine’s function over time. To mitigate this, it is important to clean pockets regularly and remove any lint before carrying a magazine, ensuring it remains reliable and ready for use in emergencies. In addition, because the rounds are not fully covered, there is a possibility of ammunition becoming dislodged during carry—particularly in more active or demanding environments. Some magazines are more susceptible to this than others, but it remains a consideration for anyone evaluating the ENDUO system.
Models and Options
The ENDUO is available in both universal and magazine-specific versions:
Universal ENDUO: Attaches to most standard pistol magazines using high-bond adhesive tape. After a 24-hour curing period, it’s ready for use. The adhesive is strong yet removable, allowing reattachment to another magazine with a fresh strip.
