Rounded IWB Holster - Inside Waistband Concealed Carry, Optics Ready

In this review the Rounded IWB Holster from Concealment Express is judged as a solid option for concealed carry users who prioritize comfort, consistent fit, and adjustability. Built from.08 Kydex formed over CAD-designed aluminum molds, the holster delivers precise retention and a repeatable fit for the FN FNX 45 while remaining thin enough for everyday wear. The single biggest reason to buy is the combination of an adjustable Posi-Click retention system and cant options that let the user tune draw feel and carry angle without tools.

Key Features

• Precision-formed Kydex: The.08 Kydex molded over in-house aluminum molds provides consistent fit and durable construction that holds its shape over time.
• Adjustable Posi-Click retention: The audible click confirms the firearm is secure and retention can be adjusted quickly for a tighter or easier draw.
• Adjustable cant: Cant ranges from -5 to +20 degrees so users can set AIWB, strong side, SOB or cross-draw carry angles for comfort and concealment.
• Claw compatible: The design accepts a claw kit to tuck the grip toward the body and reduce printing when wearing an untucked shirt.
• Full length sweat guard: The sweat guard and rear sight shield protect the pistol and user while preventing scope or optic interference against the body.
• Fiber-reinforced stealth clip: The belt clip is designed to hold the holster discreetly on a 1 1/2' belt while keeping the profile low and concealed.

Who It's For

This holster is best for FN FNX 45 owners who want a reliable inside the waistband option that is tuned for concealed carry with an untucked shirt. It suits daily carriers who value an adjustable retention system and the ability to fine-tune carry angle for appendix, hip, or small of back positions.

Those who want a minimalist leather hybrid or a rigid outside the waistband platform should look elsewhere; this is a molded Kydex IWB piece that favors hold, repeatability, and protection over soft concealment or full outside-the-waist comfort.

Pros & Cons

Pros

• Consistent, lightweight construction from.08 Kydex that feels comfortable for all-day wear.

• Claw compatibility and adjustable cant minimize printing for better concealment.
• Full length sweat guard and rear sight shield protect both firearm and wearer.

Cons

• Rigid Kydex profile may feel bulkier than some soft or hybrid holsters, especially for those extremely sensitive to inside-waistband thickness.
