I am wearing a full-lug 4” Ruger GP100, in a Milt Sparks VM-2 holster, using my new Tenicor Zero belt. Thus far, it is quite comfortable. The cylinder is, of course, relatively wide, which does not present a comfort problem, and things are nicely streamlined at the muzzle end, whereas a wide-body railed auto might be less-comfortable, and more difficult to wear, all day. An autoloader, of equal weight, carries much of its loaded weight, in ammo, which is above the belt, while being carried, whereas a revolver’s center-of-balance is lower, when being carried, as the belt passes over the cylinder, when carried in this holster.
First impressions, with this combination, are favorable.
