Mine was not reliable enough for carry. I had several of the lockbacks earlier guns had in this model. Also the magazine release is prone to pop the mag out in pocket carry. Looking at the online reports of Glock changes, it looks like mine (bought new July 2014) had most of them, maybe I needed the latest magazines. But with the magazine popping out in my pocket, I dumped it on a buddy who is a Glock armorer....
