Softer shooting? +P ammo??
I think that is mighty subjective. You will not get a definitive answer.
Had both pistols. Love the P2000sk.
But I love the P30sk more. I currently have that one.
Any sub will be a bit snappy, even in 9mm. But felt recoil? I think that varies more from guy to guy than it does gun to gun. Ammo from the same box will generate the same impulse.
One guy says the P2000sk is easier on the hands, the next guy says no, the P30sk is the money.
I never noticed a difference. There may indeed by one (not measurable by feel in my opinion), but if there is, it is negligible.
