I have a soft spot for the little Mustangs, I have 3, a regular model, a Plus II, and a polymer framed XSP. They are a hoot to shoot, and my wife loves the little Plus II model. They are all 3 suprisingly accurate mouse guns. I'm sure you'll like yours, congrats. I picked up some Metalform brand mags from CDNN Sports, just checked, they have them in stock at decent prices if you're in need of a few.
