@CoQ_10@Curvin@WashedOutGundamPilot@elftummy@mmmfeet It’s the Smith & Wesson M&P 2.0 Subcompact in .40 S&W. They made them in 9mm and .40 when they first came out in 2019, but only the 9mm models are currently listed on the Smith & Wesson website. But you can still find factory new .40 versions on Gunbroker.
Mine was bone stock when I bought it, but I added a set of Trijicon night sights a few years ago and just recently added an Apex Forward-set trigger.
