I picked one up off Armlist for $300 from a private owner. It was new in the box, optic cut, with night sights, so I figured I couldn't go wrong for the price. I primarily carry a G19.5 and 43x, and mostly only shoot glocks at the range. For the price, it's a lot of value. I shot it extremely well right out of the box, which actually surprised me. Even thought it felt different, not in a bad way, my accuracy did not suffer.
I don't absolutely love the trigger and the safety dingus sometimes gives me issues. It could be my grip and finger placement, but I've noticed that I don't engage it right perfectly, it hangs up a bit. Not to the point that it won't fire, but I can feel the safety 'pop' into place if that makes sense.
