In all seriousness, tho - why?
About the only market as over-saturated as the polymer striker pistol market is the AR market. There are sooo many decent to very good AR options already, so many parts available to build your own - what does Glock think they are going to bring to the table at this point?
I mean, if you're finally going to branch out from making the same thing for 30 years, wouldn't you at least try do something interesting and different? This is kind of like if Honda made nothing but 4-door sedans for decades, and then suddenly said, "Hey! We're making a mini-van now, too!!"
Of course, the diehard fanbois are going to trip all over themselves to own one. But for anyone who isn't a complete single-brand kool-aid drinker, I just don't get it.
