Although physics can't be fooled, hands can.
To me, revolvers recoil less; I don't know why, maybe the impulse of the slide flinging around up there doesn't feel as good to me as "one-shot" and it's over.
For me, I notice the same thing with shotguns. It's definitely true that gas operated shotguns have less felt recoil, but I'd rather feel the recoil from a double for the same reason as above.
I have two full-sized Colt 1911's, and a 1955 S&W - I like shooting the revolver better.
However it works for you, the 625 should be a great gun for you.
