I bought one of the first ones when they came out (2011 or 2012?) and don't have one complaint about it. It will kill a possum I heard.
Edit:if I'm not mistaken the xds was designed around the .45 ACP cartridge from the start. It was later on they chambered them in other cailbers and offered the longer barrel versions. A marketing strategy I suppose?
That's what I recall as well. What sold me was the vid of Leatham shooting one with 255 gr SWC loads. Then he shot a mag full of mixed rounds, from the lightweights up to the 255 grainers, with no hiccups. To somebody who came up when 5" 1911s typically choked on anything but 230 gr Ball ammunition, that was near miraculous.
I bought one on the old SSE1, and really liked the way it felt in the hand. YPMV (Your Pants May Vary) but I found it easily pocket-sized. With some of those new(ish) dedicated CCW pants, even the 4" version wouldn't be a problem, even in a proper ankle holster. It's slim and trim, feels good in the hand, and pointed naturally for me. I've seen several times a seemingly insignificant size difference of a 1/4" or so here and there made a huge difference in concealability and carry comfort, and this gun was an excellent example.
With the extended mag and grip, and a 4" barrel, I think it may supplant the LW Commander in my mind as the ultimate all-around carry & home defense pistol. The one thing I hate about it is the ship's prow-looking cut on the front of the slide; apparently the designers wanted to make sure it had a feature to gouge flesh and create an obvious bump in your clothes. If I get another one, I think it'd be time for
Attack of The Belt Sander.
My problem was that when I bought it, the SSE1 process was on it's way to being legislated out of existence, so I left it unfired, thinking it would go way up in value, which it did. I never got to fire the thing, as it rapidly got to the point I pretty much had to sell it! After I move out of CA, I should be able to replace it for less than half of what I sold it for.
