I bought one in Mid March and liked it so much I did something I have never done before, I bought a second one just because.
I stopped counting after 3000 rounds and it has been my daily carry for months.
I cringe when I hear "primer marks". I have a few mouse guns and everyone of them leaves an elongated swipe on the primer. I have found no down side to primer swipes with any of my guns.

As a RSO I can't tell you how many people have fired my gun and immediately picked one up.
To anybody looking for a small high capacity semi auto, test drive one of these wonders. Bring your billfold.
