My favorite pocket/ankle pistol has an upgrade. The new XD-S OSP from Springfield Armory is now optics ready. The test model shown here came with a Crimson Trace CTS-1500 mini red dot sight pre-installed and ready to go. In fact, when I took it to the range to zero the optic, I found it was already dead on. And I do mean precisely. At 15 yards it was shooting right through the red dot superimposed on the target.
