I picked up this M&P9 CORE this week—I've really enjoyed my 8-year-old M&P40 but my new post-cataract artificial lenses, while giving me awesome distance vision, have taken away some of my near-focus ability, so I'm moving more to optic-sighted pistols. I tried a G17 MOS but between the lack of suppressor-height sights and the different grip angle I couldn't warm up to it.
