The Bianchi Assent Pro-Fit (brand part no. 32831) is an outside-the-waistband concealment holster built in Bianchi’s size 13B pattern, sized for 4-inch-barrel duty and carry pistols including the FN FNS and 509, the Ruger Security-9, the Glock 19/19X/23/45, and several H&K, S&W, and Walther models. Bianchi builds it from a vegetable-tanned leather laminate over a thermoformed synthetic liner and finishes it in tan. It’s a strong choice for daily concealed carry where a slim, high-ride profile matters.

Key Specifications

• A tan leather laminate exterior pairs a vegetable-tanned outer layer with a thermoformed synthetic liner for structure that holds its shape.
• GLS (Grip Locking System) retention automatically locks the pistol in place when holstered and releases with a natural middle-finger sweep on the draw.
• The belt slide mount rides high on the hip for a fast, natural presentation.
• Belt slots are cut for belts up to 1.50 inches wide, pulling the holster close to the body to reduce printing.
• Size 13B is Bianchi’s pattern for 4-inch-barrel service and carry pistols such as the FN FNS/509, Ruger Security-9, and Glock 19/19X/23/45.
• GLS retention adjusts and customizes to secure fit without extra tools.
• This is a right-hand draw holster.
• An open-top design keeps the presentation fast and natural.
