The Tactical 5 inch XD pistol utilizes the same superior safety features standard on the XD models and incorporates a longer sight radius for even better accuracy. This time the Springfield engineers have outdone themselves, defying the laws of physics, adding material where needed, shaving it away where it's not ... cramming 14 rounds of 45 ACP punch into a polymer frame that is not perceptibly larger than the one Springfield use for their 9mm and 40 cal. XDs.
