As I mentioned above, I am hesitant because it's mostly made from polymer. 9MM may not be near as stout as .223 but it's quite bit more powerful than .22LR.Tagged because I want to see Simon’s opinions.
I handled one of these at the shop. Two opinions 1) yuck it’s cheesy plastic and PCCs are stupid, carry a rifle and 2) this seems pretty cool, lightweight, takes different mags, trigger OK, bolt has a decent looking extractor. To be honest it peaked my interest as I like PCCs and enjoyed my AR9 before I sold it to a friend. I didn’t care for the plastic but I did like the weight.
I like the idea of being able to shoot the same caliber and a lower cost round, but other than that I don't see other benefits.
