It's better to be able to cock the hammer, in case you need a careful shot. I used to fill in a bit of Tig Weld material, then serrate the rear of the bobbed hammer with a checkering file. By "starting" the hammer rearward with a short pull on the trigger, it was then easy to thumb cock it the rest of the way. As I said, tho, the Cm9 Kahr is a much better choice for many reasons, than any revolver. It lies much flatter in your pocket, holds 7, hits harder with each shot, is faster for repeat hits, reloads 3x faster, its spare ammo "carries" much more easily for ccw, it's much less fragile or exposed to debris, sweat, or precipitation than any revolver. it can be had with a laser built into it or luminous sights, too. The snubby revolver can't have the luminous sights, without spending $300+ on custom work, that is.
