I've got an old Gen2 Glock 21 and a newish Gen3 Glock 36 and love both of them. Great choices for .45ACP SD handguns. I've shot both the G26 (a friend's) and G36 (mine) and there's no doubt the G26 is a softer shooting gun. I've had a number of people, however, comment on how easy the recoil of the G36 is to control, for a big bore compact. Also, I find I shoot my G21 much better than my G17. Not totally sure why, but in the big gun the .45ACP feels quite controlable.
