586 revolver rigs....
There are a few decent brands for a 4" S&W 586 revolver
if you have the time & $$$ for high quality rig.
Contact the shop or holster firm first to make sure you'll be aware of the design or length of time.
Back-orders & delays are common due to huge demands.
See Kramer Gun Leather, Don Hume, Ted Blocker, Tex Shoemaker(he did the leather holster used by Deputy Rick on AMC's hit
The Walking Dead), Galco, Mitch Rosen, Wright Leather Works, El Paso Saddlery, DeSantis, Kirkpatrick Leather, Mernickle, Milt Sparks.
Some gun owners & CCW license holders like horsehide or exotics for strength/looks. They cost more but you'll have the holster for years.
