In the end, I bowed to the Wisdom of Tex.

Now I got to wait to hear the story because I am surprised, but those Commie Austrians make good guns. 
Not much of a story. The deal was better on the Glock than the Springfield, the ergonomics of the Springfield were not sufficiently better than the Glock to sway me, they didn't have the Springfield package I wanted, and the ubiquity of Glock means cheaper and more plentiful aftermarket accessories. It was a bang for buck decision.
The simpler manual of arms for the Glock also appealed for the sake of the warden. It's a weapon she can just point and shoot. That means a greater chance she'll kill me outright, rather than wounding or disabling me.
Also, the Croats who manufacture the XD's are more commie than the Austrians.
Morning, mucha-I mean, young men.
Yeah, you don't want her to start thinking before popping you. 
Yep lots of goodies! Put some quality night sights on it first though. Amazon has some good deals on Tru Glo's. Also you can use an X Grip adapter and use higher capacity G22 magazines in there perfectly. FYI if you did not know it the magazines for 22/23's are interchangeable with those for 31/32's. Also you can buy a G32 barrel and swap it out in about 3 minutes to shoot .357 Sigs.
It is a G22 so doesn't need the extenders. And the ability to switch out to .357 Sig also factored in to my decision.
I still like the 23, compact without making me dangle fingers. So when I've recovered from this purchase I'm inclined to get a 23 to be the warden's gun.
I have the 23 and can vouch for that choice. Don't know if she's planning to CC, but it may be a little large for that duty, for a woman at least.
Can't convince her to CC yet. Working on it. But she's a paraeducator in a classroom full of autistic kids, so even if it was legal to carry at school here, would not be a good idea. So she'd only be carrying for shopping trips and hanging with friends.
