A proper belt and holster handle the weight distribution of a hi-cap auto just fine carried AIWB. Any 6-8 shot revolver, no matter the weight distribution, is harder to carry because of the shape of the gun. Holster enhancements like muzzle pads and claws keep the holster/auto tight up against your body without outward tipping. The weight is distributed through the belt around the hips.

OWB the revolver may carry better because of the weight distribution with a floppy holster on a thin, soft belt. However, a fully fastened auto holster on a wide, stiff belt will carry just fine, especially with new features like a muzzle pad to keep the grip tilted in.

In short, if you have problems carrying a gun because of weight distribution issues based on a grip full of rounds, those issues have been resolved by numerous belt and holster makers. If I’m going to carry 40+ oz of gun with 6 bullets, or 40+ oz of gun with 18 bullets, I know why I’m carrying the SA.
