The Bianchi Assent Pro-Fit (brand part no. 54501) is an open-top OWB holster built in Bianchi’s size 04 pattern for full-size 4- to 5-inch-barrel autos, including the Springfield Armory XD, the Sig Sauer P220, and the FN FNP. Bianchi gives it a low-profile, body-hugging shape in black leather with GLS (Grip Locking System) retention that secures the pistol the instant it’s holstered. It rides high on the hip for a clean concealed-carry or range-day profile.
