10 Best Iwb Holsters 2025 in the United States

The CYA Supply Co. Base Optics Ready IWB holster is a solid choice if you need a comfortable and customizable holster for your HK CC9 pistol. It’s made from Boltaron, a robust material that’s tougher than typical Kydex, offering better resistance to heat and impacts, so it should last longer and protect your firearm well. The holster’s slim design helps reduce printing (the outline showing through your clothes), which is great for everyday carry and discreet use.

Its “Posi Click” retention system gives a clear click when your gun is securely in place, and you can adjust both how tightly it holds the firearm and the angle (cant), allowing you to find a comfortable, natural draw. It also features a long sweat guard to protect your weapon from moisture during wear. Compatibility-wise, it’s custom molded specifically for the HK CC9 and is optics ready, meaning it can fit pistols with mounted sights, which adds versatility.

It’s designed for right-hand users only and may not fit other pistol models, so it’s best suited if you own the HK CC9. Some users might find the retention adjustments a bit tricky at first, but once set, it performs reliably. This holster is lightweight and comfortable enough to wear all day, making it a good option for those prioritizing comfort and secure retention in a discreet setup.

This holster by Concealment Express is designed specifically for the Sig Sauer P229 with a rail, making it a solid choice if you own that firearm. Made from 0.08 inch thick Kydex, the holster offers a custom-molded fit that feels sturdy yet lightweight at just 2.5 ounces, so it won’t weigh you down during daily carry. It features an inside-the-waistband (IWB) design that helps with concealment, and the adjustable retention pressure and carry angle (cant) give you some flexibility to find the most comfortable and secure fit for your body and draw style. The retention system includes an audible 'posi click' lock, which adds peace of mind by confirming your gun is locked in place but still easy to draw when needed.

Comfort is enhanced with a full-length sweat guard to protect your skin from irritation and belt clips designed for secure attachment. On the downside, this holster is made for right-handed users only, and the belt clip is made from ABS plastic, which might not feel as durable as metal options. Also, while Kydex is excellent for durability and retention, some users may prefer leather for comfort against the body.

The holster comes with a lifetime warranty, showing confidence in its quality, and has received positive customer feedback with a 4.6-star rating from over 10,000 reviews. If you’re specifically carrying a Sig Sauer P229 with rail and want a reliable, adjustable, and comfortable IWB holster made in the USA, this model is worth considering.

The Concealment Express IWB Holster for Sig Sauer P365 is made from durable KYDEX material, ensuring a sturdy yet lightweight construction. It promises comfort for inside-the-waistband carry with an untucked shirt, making it suitable for concealed carry. The ‘Posi-Click’ retention feature offers an audible click when holstered, providing a secure fit and ease of mind. This retention is adjustable without special tools, allowing you to customize the retention pressure to your preference.

Additionally, the holster's cant is adjustable from -5 to +20 degrees, which gives versatility in carry positions, including appendix, strong side, small of back, or cross draw. The holster is claw compatible, designed to reduce printing by angling the gun's butt towards the body, enhancing concealment. The fully enclosed trigger guard adds a safety layer by preventing accidental discharge. A sweat guard and rear sight shield contribute to comfort, particularly in warm conditions.

The holster is designed and manufactured in the USA, reflecting high quality and durability. However, it is specifically designed for right-hand use and may not be suitable for left-handed users. It comes with a lifetime warranty, suggesting confidence in the product's durability. This holster is ideal for those who carry a Sig Sauer P365 and prioritize security, adjustability, and comfort in their concealed carry equipment.
