Nice review and pictures!
My Shield is on the way, glad to see you like it and a good idea to have both so there is a familiarity with the guns.
I do own and like Glocks, but how much simpler is a Glock than an M&P? I may pick up a full size Pro model if I like the Shield. Speaking of, I should check on that thing, the gun store should be calling any day now!!!!!
