Is this a Ford vs Chevy kind of thing? I don't get it. I own more S&W's than any other brand of pistol. I also own a Sig P365. My Shield is a great pistol, but it is much larger than the P365. The P365 has a better trigger and much better sights. It carries and conceals like a dream. I'm still a S&W fan, but Sig has done something with the P365 that is truly amazing.
I hope S&W is working on something to compete with the P365. I will buy one. But, for the time being, there isn't anything out there that matches the P365 for size, capacity, concealability, trigger or sights. The package Sig put together in the P365 is terrific.
