Well, I'm 6'4" and 280, so I figure I'm close in size. My first handgun was an xD45 purchased 12-13 years ago while doing a LOT of motorcycle riding in Arizona. Carried in an OWB CQB (I think) retention holster. Since moving to MA (10 years ago, escaping to TN in 6 months) I have purchased and carried several guns. I first carried a Kahr k40, then an S&W Chief Special 45, then an e-Series 1911, followed by my current EDC, an xD45 mod.2 which I carry at about 3 o'clock IWB in a Crossbreed SuperTuck. There was also briefly a Shield in 9mm but I didn't like it much, even though it concealed well IWB at 4 o'colck. Big fan of Crossbreeds, have several for several firearms.
OP, I think you'd like the double-stack the Springfield provides, and the "Grip Zone" does allow a more confident draw. I carry mine 9+1 with multiple spares. One nice thing is that like Glock, pretty much all Springfields break down the same way and have the same controls. they're actually easier to disassemble. I have 4 between Lady Radtekk and I, and she has a G26, so I have plenty of practice with both. I don't have a problem with Glock, just found I liked Springfields and stayed with them. Also, the standard size xD45 13 round magazine fits in the Mod.2 although since it's longer it does look weird. I wouldn't carry that way, but it is nice.
If I was down there I'd invite you to try them out and see, but house-hunting trip is this weekend and that's a few too many to travel with, TSA gets weird when you have a suitcase full of handguns.
Just my .02 for what it's worth.
