From The DalyCaller.com, By John Taffin, GUNS Magazine, 07/31/2013 – We can know our ABCs and watch our Ps and Qs but for Springfield Armory “X” marks the spot. The Springfield X-guns have been very popular beginning with the XD, then came the XD Compact, the XD Tactical, the XD(M), the XD(M) 3.8, the XD(M) 3.8 Compact, the XD(M) 5.25 Competition, and the XD-S .45 ACP. The beat goes on as the latter, previously only offered in .45 ACP, is now available in 9mm. The “S” stands for single stack. Now why would anyone want a single stack .45, or 9mm for that matter, in these days of high-cap magazines? I can think of two great reasons, namely a smaller pistol is much easier to conceal than a larger counterpart and is certainly easier to pack all day.
