I have a lot of experience with an M&P Shield because I was a tower guard in a prison and had to shoot every week. I don't like it. It feels like shit in my hand, almost like it's an airsoft to 9mm conversion or something. Replacing the trigger with an Apex is almost a necessity too. Grip angle and texture are subjective at best, but I do like the replaceable backstraps. a safety has no place on a duty pistol meant to be carried hot anyway, because that's just one more thing to have to think about that could get you killed if you forget. As for price, if I'm already looking to spend $500, I may as well shell out a little more for the product that has more aftermarket support than anything else on the market. Limp wristing shouldn't be a problem if you're a man. I've never in my life had a limp wrist malfunction with any weapon. That's a onions and femoid problem exclusively.
You can like whatever you want, but don't think that just because you bought it, that it's better than its competition. Example: I love slav gear but it really doesn't compare to western gear in quality or performance.
