David,
IMHO Once you develope consistant practice habits, recoil w/any of the above pistols will be a moot point. Recoil is a subjective thing, but tends to diminish in importance as one becomes more and more accustomed to his handgun. You may already know this, but since I don't know your experience w/handguns, please excuse me as I do not wish to insult you with info you may be familiar with. There are some loads that have less snap than others, but I think that some gun writers who have nothing better to say, as well as some guys who like to brag about how they suppossedly brussed thier foreheads with the "kick" of the horrendously powered gun that they once shot is the major reason for the recoil issue.
I believe that the 239 has slightly, yet hard to notice more "recoil" than the two others. As for the glock, it is said that the plastic and higher grip to bore axis lessens recoil a little; but with 9mm you won't get much w/any of the above anyway. It can give arguements for why I like SIGs better than Glock, but when it realy comes down to it, it depends on what fits YOUR hand and circumstances the best. I can not address those issues w/out more info.
If you have arthritis, a major back problem, or happen to be one of the minority who do happen to be very recoil sensitive, this is a legitamate concern. If you have access to a shop or friends who will let you check them out and shoot them at the range, this will give you the BEST idea. Double (plugs AND muffs) hearing protection is one of the best solutions to flinch IMHO. If its not flinch, but quick sight pick up thats the concern, I don't know that any one of those will give you measureable difference above another. Grip comfort and pointability will have more to do with that issue than recovery due to recoil.
One last thing. Any of those weapons will serve you very well, but if you are able to check out the 225 model, it is worth the look. It is the small model, between the ones that you mentioned, with a good looking square trigger guard. It seems to feel best in my limited experiences, with those who have average or small hands. Its got a full hammer, yet smaller for CCW than the 226. Q's feel free to contact me

Best wishes in your quest for the best!
