I have a Glock 23 and an XD 9mm and like them both, but the XD is much easier to get back on target. .40 cal is long known to have a nasty recoil because they are trying to cram more firepower into a smaller case. I've tried different types of ammo to see if that helps and some ammo does indeed have less recoil than others. There is all sorts of science and math involved in velocity, pressure, etc..but you can search that on your own.
I have heard, though, that the Glock .40 cal pistols seem to have more recoil than others. But I'm not planning to abandon either one of them....I just use a lighter round to practice with on the Glock cause 200 rounds or so of that, and your hand will start to hurt, and I start to anticipate the recoil, which destroys your aim. I can shoot the 9mm all day and not have any problems, though.
