I suspect this will go over very well with a large segment of the Glock/M&P crowd. My initial negative gut reaction is similar to many others here, but I can see the appeal for a lot of people. Especially considering the price point.
Sooner or later, a fully enclosed optic will be the norm, and having something that isn’t the size and shape of a US Mail box has some appeal.
With that said, I imagine it’s just a matter of time before they come out with mounts that will work for some other striker pistols.
