It took me along time to decide if this was the holster for my GP 141 S/S revolver, but patience produced a perfect fit for the Ruger GP100 4-inch series revolver.
The holster is a rock-solid example of Bianchi quality. It is heavily stitched throughout and the dye is uniformly applied.
When you first slide the gun into the holster, press down on the gun just a tad and you will feel the cylinder fall right into its detent in the holster. It will take very little effort to roll the hammer strap into position for snapping into the robust thumb snap, which is mounted in a substantial piece of holster real estate. One feature that a thumb-break holster must have (for me) is a rigid thumb snap and the Bianchi 111 Cyclone excels in that area.
The holster exhibits two pathways for strapping this holster onto your belt; strong side through the obvious belt loops and weak-side, cross-draw through a slot that is separate from the two primary slots. The cross-draw position is nearly perfect for sitting and rides butt-forward for easy retrieval of the revolver. I prefer the cross-draw position, because I shoot long guns on my left side although I am right handed; the cross-draw position provides a smooth transition from rifle to handgun without my having to change shooting positions. My right hand (strong side) simply falls down from the forearm of the rifle to the butt of the handgun. It can’t get any simpler than that.
Some complain about an open-bottom holster but I have no problem with them. The front sight is well protected, although there is no rear sight protection. I believe the 5BHL has a sight flap but the trigger is exposed. You would have to hit the rear sight directly to damage it in this holster.
One thing that I demand in an OWB holster is trigger protection and the Bianchi 111 Cyclone holster does that very well; the trigger finger simply slides over the leather and is pushed out of the way of the trigger – as it should be.
The holster is fashioned in a way to present the lowest profile possible with this style of holster. Only a pancake holster style could do it better. With a little ingenuity, I could make this holster a “chesty” rig, if need be.
If you are looking for an excellent holster to house that 4″ GP100 series handgun, this would do it for you. I will attest to its fit with the GP100/GP141 revolver and it should do well with the S&W 586/686 or other 4” K/L (medium) revolver frame.
