not to argue the point at all but my p220 just came with houges. nope i didn't order it that way.
my investigation into this-i had never even thought about the ergonomics of grips and all the pallaverin on the subject went rat over ma head-lead to a conclusion. i have a large hand but short fingers-well short in ratio to the palm. i found, after lookin around, that a regular grip size was, like you, a little uncomfortable. too much of the finger wrapped around the trigger and my fingers were touching the palms of my hand. not enough gun to hang on to, i guess, is a pretty good way to describe the feeling.
some of the extremely built up grips felt as though i was holding the weapon in my finger tips. i have yet to find a grip that is perfect-well not a great deal of investigation here-just a couple of places that had grips on handles, if'n ya unnerstand.
the houges felt as good as any without a custom order-who knows with me, that might be next. i have houges on tha p239 and tha p220 came with em.
just my thinking.
