If I had a 9mm auto loader, and no revolver in 38/357 I'd consider a 9mm revolver.

If I didn't reload, I'd consider a 9mm revolver for the cheap (relatively speaking) available ammo, and put up with the mandatory use of moon clips.

If I shot competitively and needed the absolute fastest reload, I'd consider the 9mm revolver.

As someone who already reloads 38/357, doesn't own a 9mm auto loader and isn't fond of using moon clips for range sessions (but LOVES them for the ease of loading and unloading outside of the range) I opted for the 627 PC .357.

Moons if I want to use them ( I keep my carry ammo loaded up in the moon clips), and no moons for range sessions.

In certain cases, I see a nice niche for 9mm revolvers... but for my own purposes, the .357 makes more sense.

S&W1911... that 929 is one great looking revolver!!
