I considered the 227, but I'm really a huge fan of the 220. I love my 220 Elite Dark and I like that it's relatively slim.
With that said, I've heard good things about the 227 and that the ergos are VERY close to the 226 - as they should be.
I'd love to shoot one, but I don't feel it calling to me at the moment because I'm still in love with my 220. I DO want a 226 though. Still saving pennies for that one. Either a MK25, Combat, or Extreme. Don't care which really - just whatever is available when I'm ready to buy.
