I shot my new G19.5 next to the M&P 2.0 Compact yesterday, total of 800 rounds, 400 rounds evenly split. Took a while as I only have four M&P mags, plenty of Glock mags...brought seven with me. There were zero malfunctions of any kind and both were a joy to shoot IMO.
I will say the 19.5 shot like a Glock, I was more accurate with it as I am used to shooting Glocks but the 2.0 Compact was a bit easier to shoot with its ergo's, light trigger. It was a bit more difficult to feel/hear the reset than the Glock but still, good enough for what it is. I do like the lack of finger grooves on the 19.5, my favorite thing about it. The finish would be next. I see no difference in accuracy between this Gen 5 and my other Glocks...all are more accurate than I could ever be as a shooter.
However, one big negative was the BTF and light ejection pattern of the lighter 115gr ammo. Now I shoot Glocks all the time, as I have a few and none put brass to my face, even with lighter ammo. The 124gr FMJ and all self defense loads ejected normally. However, as I shot more, the brass started to eject properly, though still not as strong as the hotter ammo. The 2.0 had no issues with the ejection pattern, no matter the ammo. Regardless, both are keepers, I am a Glock fanboy but this new 2.0 is an excellent alternative. Biggest negative about the 2.0 is the gritty take up and rough grip texture. Not for shooting, it worked great but for conceal carry, on the skin, not the best feeling.
