Virtually all modern double action revolvers will quickly develop the ring.

This is due to the fact that the cylinder locking bolt is specifically designed to actually "ride" on the cylinder for most of it's rotation.
When metal rubs metal, you get a wear mark.
Slowly cock a modern revolver, as the hammer comes back, you'll hear a distinct "click". That's the cylinder locking bolt dropping back onto the cylinder. The bolt will ride on the cylinder for most of it's rotation.

You can also see this process. Hold a revolver up to the light and look between the bottom of the cylinder and the frame "window" as you cock the hammer.
You'll see the cylinder locking bolt retract, the cylinder start to turn and the locking bolt dropping back onto the cylinder. The bolt will maintain contact with the cylinder as it turns.

The only modern DA revolver that doesn't necessarily get the wear mark is the old Colt action like the Python and Detective Special.
These are designed so the bolt doesn't ride the cylinder.
However, from opening and closing the cylinder and normal use, these too will get the wear mark.

In short, the wear ring on a revolver is a feature of the design and is entirely normal.
