OH. My. God. I want one.
The Ice Test. We filled a tub with water, dropped in the XD with a magazine and put it in the freezer for a week. Breaking it free by dropping the "gunsicle" onto concrete, we let it thaw out on the way to the Oak Tree Gun Club, our favorite outdoor handgun range. Upon arrival, we inserted a fresh magazine into the XD and fired. We fired about 150 rounds before wiping it down and lubricating it. Result: zero malfunctions.
The Dirt Test. Following the lead of the Glock tests, the XD was "caked, covered and buried alive in soils of varying consistencies." We used everything from dust and ash to moist dirt and sand. We fired 100 rounds after subjecting the XD to each of the five kinds of dirt, for a total of 500 rounds. Predictably, sand proved the most challenging to its mechanism. After burying the gun in sand, then stepping on it to grind it in, we took it out to shoot. The slide cycled noticeably slower, but the gun never jammed. Result: zero malfunctions.
The Mud Test. The XD was covered with thick, gritty mud. After a quick shaking off, it was fired 100 times. Mud went everywhere from the recoil, mostly on the shooters, some on bystanders--it was amazing how much sprayed off the gun. Still, the gun kept working. Result: zero malfunctions.
The Water Test. Fully loaded, the XD was left completely submerged, removed from the water and fired. This was repeated 10 times, firing 10 rounds each for a total of 100 rounds. Result: zero malfunctions.
The Chemical Degreaser Test. Using GunScrubber, all lubricant was removed from the firearm. After making sure there wasn't any lubricant remaining on the firearm, the gun was fired. Glock's test fired 100 rounds. We fired 150. Result: zero malfunctions.
The Tire Test. We placed the XD on a gravel surface, then had shooting champion Mike Dalton drive his Toyota Tundra repeatedly over it, then park on the weapon. We then retrieved and fired it 100 times. Result: zero malfunctions.
