What is the opinion, good and bad, of using the SA XD40 for IPSC competition? Would it be better for Production? All input is appreciated.

Springfield had commissioned engineer Charles Fagg of Tioga to analyze the matter. Fagg's report of April 18, 2002, includes the following statements. "Confusion exists as to the proper classification of the firing mechanisms of the Glock 17 and the Springfield Armory XD pistols. This confusion stems from the ambiguity of the terms, 'single action' and 'double action'... The terms 'single action' and 'double action' are archaic and have little applicability to many, respected, semiautomatic pistols."
The word "archaic" is significant. Fagg sums up the matter as follows: "CONCLUSIONS: 1. Neither the Springfield Armory XD nor the Glock 17 qualifies as a single action pistol. 2. Neither the Springfield Armory XD nor the Glock 17 qualifies as a double action pistol. 3. Both the Springfield Armory XD and the Glock 17 will fire if the firing pin is released from the ready, or carry, position unless it is intercepted by the automatic firing-pin block. 4. Both the Springfield Armory XD and the Glock 17 are designed with an array of safety features that, if maintained properly, virtually preclude a discharge unless the trigger is pulled or a chambered round cooks off in a fire. 5. From a safety standpoint, there is no basis upon which to choose between the trigger mechanisms of the Springfield Armory XD and the Glock 17 if the force required to pull their respective triggers is similar."

From Guns & Ammo -By Dan Johnson said:Defining The XD
The XD is correctly classified as a single-action design, meaning it is fully cocked by racking the slide. Most single-action autos have manual safeties, but the XD's Croatian designers eliminated the need for such safeties by adopting the Glock-type trigger safety as well as an internal firing-pin block. They also added a grip safety. The XD is a very safe design, but its single-action designation has confused some.
The XD is a true single-action internally but externally operates more like a double-action-only handgun. There are no manual safeties to disengage beforehand, and the trigger takeup has the feel of a light (very light) double-action pull before reaching a final single-action release. OK, I'll say it. The XD operates like a Glock with a grip safety. As with the Glock, the trigger design does not fit any traditional classification, so Springfield coined its own terminology and dubbed it the USA (Ultra Safety Assurance) trigger safety.
Inside The XD
The XD is a single-action design in that the trigger does not #### the striker. But the XD trigger does perform more than a single function, as do many other modern single-action designs. When the trigger is pressed, the trigger bar moves forward, and a lever in the frame pivots upward, disengaging the striker block. It's important to note that this disengagement occurs during the final stage of the trigger release. The striker-safety lever moves up in unison with the sear release. This means the long takeup of the trigger serves no mechanical function. The long pull does enhance safety, however, and performs much the same as a two-stage military-rifle trigger.
