Just picked one up with the thumb safety. Ergomomics are great even with my big paws. My wife has a XDm and this was this first striker fired gun I've shot and I liked it a lot but I like the M&P so much more. I like the way the trigger on the M&P stacks up before breaking which for me makes rappid fire shot easier and quicker without the occasional shot breaking sooner than expexted like I have had with the XDm. Very accurate and easy to shoot but like others have reported mine seems to shoot a bit low. Only got a hundred rounds of Wolf down range so far and havent had any failures yet. Very happy with it so far and the M&P might just replace the 1911 has my favorite pistol. I see a M&P 45 in my future.
