When I practice with my revolvers, I load 1 live round and the rest dummies (with the cylinder swung out and randomly rotated between each trigger pull). So, on average, I get 4 clicks per bang for my 5-shot S&W69 .44mag, and 5 clicks per bang for my S&W686 .357mag. I learn MUCH more from the clicks than the bangs, and it saves me a lot of money in ammo ... I only need to shoot about 10 rounds per range session, because that's 50 or 60 trigger pulls, with a cylinder rotation in between each pull. It's COMPLETELY different from dry-firing, because any tendency you have to flinch is still there (because you know that it MIGHT fire on any given trigger pull). And when you get a click, ANY flinching or unsteady trigger pull is VERY apparent, but is unnoticeable on a bang.
My EDC primary is either my .44mag 69 (shot SA only) or my 10mm Kimber Eclipse 1911. I vacillate between preferring one over the other for carry. Sometimes the relatively lower powered (but still powerful) 10mm seems preferable because of its 8+1 capacity and a faster reload from two easily carried extra mags, but other times the 69 with its greater power seems preferable, because the 9-shot 1911 MIGHT end up actually being a 1-shot, or a 2-shot, etc, if it jams. (The 69 COULD also fail, but it is much less likely, I believe). I tend to shoot everything much slower than most people, so the speed advantage that most people would see with the 1911 isn't much of a factor for me.
I also prefer the trigger on the 69 ... both are very light (about 2 and a half pounds), but the revolver needs NO takeup like a semi-auto does, and it just FEELS better and lighter to me. But the Eclipse's trigger is unusually good for a semi-auto.
