I went and ordered the .45. I can always sell it and/or get a different model. (At least in the near future)
While a Glock 20sf is a little thick for me I'm sure the M&P is less so.
I chose the .45 because my Sheild .45 is a pleasure to shoot (and i shoot it well) and I think the wider, heavier gun will be even more so.
