I'm interested in how these two compare size wise, and how that affects the concealability of each. I'd been considering a move to a Gen4 G19, but with the current issues plaguing those guns, I'm nearly to the point of scrapping the idea and possibly picking up an M&P instead.
I currently carry a USP Compact, which is nearly identical in size and shape to the G19, and it works well form factor wise for me. The M&P is a bit larger dimension wise, but I haven't been able to find much picture wise -- i.e., one sitting on top of the other -- that would give me a particularly good feel for how much of a difference that increased size would actually make.
I intend to drop by my LGS sometime this week to compare them a bit closer in person (I've fired both several times in the past, but never side by side), but I know we've got several people here with fairly extensive experience with both guns, and was wondering if I could get some input on this.
