Great sight so far. Time will tell after I shoot it. Still waiting on a magazine release to be sent from Smith and Wesson. Nothing yet, even though I called in my issue 20+ days ago. Optic fits great. High quality and AMAZING optical properties! However- I can’t really shake the rig out until S&W figures out why the magazine ejects itself every 3 rounds or so. This pistol shoots lights out when it’s not self-ejecting its mag with our hand meat no where the mag release button. S&W contacted. They said they’d send a new magazine release “to try”. I haven’t seen anything yet. This is a pretty massive mistake on my end to trust the name of Smith and Wesson. I’m out nearly $900. Ugh! Live and learn I say. 🥲💸
