As an option, consider the Glock 20-10mm. Takes .40 and 357SIG barrels as well. Recoil with .40 in a Glock 20 is VERY soft, so soft it's almost funny feeling. I owned a G-35 and was planning on getting a 357SIG barrel, but the 20 with standard 10mm ammo recoils LESS than the G-35-.40. Then I read on the glock board that .40 ammo can be fired in the 10mm barrel(on a limited basis), I tried it- it worked beautifully, recoil is softer than a G-17-9mm, no joke! Got myself a KKM .40 barrel and it's great! Next I'm ordering a 357SIG barrel. Remember the G-22/G-31 are just beefed up 9mm frames. The G-20 is great, even with full power CORBON 10mm loads it's very pleasant to shoot, And I am recoil sensitive to a degree- I don't like shooting alot of .357 or .44 mag's or light 12 gages but the G-20 is no problem. It is also more accurate than my G-35 was.
