SAO, yes, SA/DA, no
...
As mentioned, either P220 standard or Carry offers very docile recoil..
But, IF you get an Elite in SAO, then I would say yes, the Beaver-tail is a good thing, as it will benefit in control of recoil and follow-up shots on target "without" the need to worry about it "digging-in" to the web of your hand.. With both my 1911's with the B-tails, this "digging-in" does not occur, but benefits the follow-up shots as mentioned..
If you decide you want a DA/SA P220, in either full size or Carry, then IMHO, you do not need it from my shooting experience with both.
It could also come down to an IF you want to CCW, then the P220 without the B-tail will conceal better without worry of shirt, etc., hanging-up on the B-tail.
If you decide that you want the DA/SA model, and go with the B-tail as well, you won't regret it being there, as the bottom line IMHO is that B-tails are both, an attribute to helping with one's grip and getting on target with follow-up shots, faster, with more accuracy, for a person owning one, and shooting one, for the first time, and up the road as well.
To be clear, if it were me buying another P220 standard, knowing what I know now, I would definitely go with an SAO Elite, without doubt.
