The Singleton

This high-quality holster is our best-kept secret and the self-reliant shooter’s best friend. 



We made The Singleton to help you get out of tight spots without the steep learning curve. This compact, inside-the-waistband holster is easy to operate and works for right-handed and left-handed shooters. And it won’t budge once you secure its 1.5-inch Discreet Carry Concepts Monoblock clip in place. 


With 20-degrees of cant adjustment, this holster lets you carry your firearm comfortably and adjust the ride height for a perfect fit. Plus, we cut it to work with slide-mounted optics and most center-to-center Wing mounts so it can fit your needs without any added difficulty.

  • Discreet Carry Concepts Monoblock clip(1.5 inches)
  • Ambidextrous
  • Fixed retention

  • Ride height adjustment

Discreet Carry Concepts MonoBlock

Discreet Carry Concepts makes the best holster clips on the market. They’re known for their Mod series of overhook style clips. The monoblock was designed to act as a direct replacement for the plastic FOMI style clips that flood the market.

Holster manufacturers can buy FOMI clips in bulk for extremely cheap so they’re the most common clip on the market. Unfortunately, Fomi clips aren’t that secure and Discreet Carry Concepts wanted to fix that problem and increase the security of all the pre-existing holsters on the market.

When designing the monoblock Discreet Carry Concepts engineered their clip for durability and function above all else but due to factors out of their control the monoblock while an improvement over the FOMI isn’t perfect on all holsters due to manufacturing inconsistencies that DCC did their best to account for.

We designed the Singleton as a purpose-built holster around the Monoblock to take full advantage of the durable and secure design.

Our singleton has 3 degrees of cant built into the Monoblock mounting making the holster even more secure, especially when you’re wearing the holster without a belt. We made sure that the cloth grabbers are angled so they’ll grab your garment or belt effectively.

Made from spring steel the clips are very thin so you won’t have to worry about the clip printing like other clip options.

The two arms on the monoblock work independently to engage the different height surfaces on the gun. Most guns have varying geometry with the frames and slides being different widths. The Monoblocks arms allow the clip to engage more for the gun making the clips contact with the gun very secure.

    I purchased the Singleton for my P365XL. The fit is perfect and the clip holds the holster securely on my Kore Essentials belt.

  3. Michael Savage

    The Singleton for my Glock 19 nailed it! I use this for my EDC G19 and it’s comfortable and functional. Great job!

    I love this holster! As always, I’m never disappointed when I get a holster from Harry’s. Besides the perfect molding, perfect retention, and comfort, I like the design. The open slot on top allows me to blow off the dust on my sights after working outdoors without having to unholster the gun. I’m really liking this new design. Better than holsters that cost double the price.

    I got this for my Sig 365xl. This is my first Harry’s holster. I have worn this holster for about six weeks for 8-12 hours a day. Cannot say anything bad about it would buy again!

  9. Brian L. (verified owner)

    I am stunned how nice this holster is. It’s optics ready and well priced. I have been wearing the last week and it’s more comfortable than another AIWB holster I have that I like very much. I would HIGHLY recommend getting the claw and wedge pads as they all work in tandom to conceal and improve the comfort of the holster.
