I have a 220, 229, and 226.
The grip on the 229 and the 226 is the same and it quite large, both in 9X19 Luger, Your standard double stack.
The recoil on my 229 is minimal.
I used to load three rounds in the mag and then stick in a +p round and then top off the mag with the 226.
That way it was a bunch of bangs and then a BANG and I knew I had three rounds left in the mag.
My 229 I can not tell a +P round.
If you need a slimmer profile than the P239 will work for you.
9mm should be fine.
There is also the option that the 220 was chambered in 38 Super. You would need a new barrel and mag to make it work.
Also Hogue makes soft rubber grips for hte 220. My 220 Sport came with them.
