So I ran across this. Details are sparse. It appears someone let the cat out of the bag before they were supposed to. It appears to be a Glock 19 sized pistol with a removable FCU that could possibly be moved from on frame to another (similar to Sig's design). It seems it is a collaboration with Magpul & the slide would be optic cut. Of course, all of this is just conjecture at this point. I find myself wondering what the price point will be. It doesn't really make sense to me as the polymer pistol market seems to be very saturated but what do I know anyway.
