I rented a Shield Plus last week with what I think was a 4" barrel version. At first I didn't think I'd like it due to the thin grip, but I ended up liking it a lot and shot it better than others in that size range. I'm seriously considering one that's optic ready but am intrigued by their new CSX E-Series with a 3.6" barrel. I hear it's improved from the original but want to shoot one first before I decide.
