Bianchi 7001 Thumbsnap OWB Holster for 4-inch Ruger GP100/Colt King Cobra

The Bianchi 7001 Thumbsnap (brand part no. 17743) is an outside-the-waistband hip holster sized for 4-inch-barrel revolvers, including the Ruger GP100 and Colt King Cobra. Bianchi builds it from trilaminate material — a closed-cell foam center, poly-knit inner lining, and ballistic-weave outer finish — for a rig tough enough for outdoor and duty-style use as well as everyday concealment. The holster rides at a 10-13 degree forward cant for an instinctive draw, and the Roll-Top thumb-break strap wraps cleanly over the hammer for secure retention on the belt slide.
