The other day a buddy of mine showed me his brand new XD-S .45 and immediately I fell in lust! It seems to be the perfect size for CCW due to the narrow slide width (just .9"). The only thing I don't like is that it currently is only available in .45 and I would prefer a .40 or 9mm. The XD-M subcompact comes in all three calibers but I can't find the slide width on the specs pages. It sounds like they are all double stack mags which will obviously make the grip wider and more difficult to conceal.
Currently I have a Bersa Thunder .380 and a Sig Sauer P239 in 9mm. I usually carry the .380 because it is lighter, smaller, thinner and more easily concealed.
Anybody have these models or have you compared them for yourself yet?
