I've had a number of XDs and an XDm. The one I kept and will never part with is an XDSC9. I had the carry package upgrade done by Springfield with XS big dot sites. Highly recommend it. Also put a set of crimson trace laser grips on it. Multiple mags. Some 10s with extension and 16s. Some holsters. My favorite is a thin IWB leather holster from Kirkpatrick leather (Kirkpatrick Leather Concealment Holsters - The Clip On Holster). Love their holsters and have many for my 1911s.
