I just bought one used, and like it. The magazine is absolute sh1t. Not that it doesn't feed properly,it does it's just thin tin type material and i don't expect it to last. I'm shopping for larger, better made aftermarket ones.
It's light and shoots very well for the short barrel. The receiver is cut to accept optics which i will install as i find the iron sights kind of...well, weird, and i shoot iron sights on all my guns aside from 1. Nothing wrong with them, they work fine just weird sight picture is all, takes some getting used to.
I'd recommend buying 1, just don't pay too much...a Ruger it is not.
