With that other style of sights, three-dots, the XD Sub-Compact proved much more accurate in my hands. Quick shots with the brand new XD Sub-Compact .40 with three-dot sights produced 1.5- to 5.5-inch groups at 15 feet and 21 feet.
During one range session, a friend of mine who works in a local police supply store helped me fire 120 rounds of Speer Lawman 9mm 124-grain FMJ ammunition through a 9mm XD Sub-Compact. In several strings of fire, we averaged 3- to 5-inch groups at distances from 20 to 40 feet, engaging targets at a fairly quick pace.
I see this drill as a true test of a personal defense handgun, and when I test firearms that can be carried by law enforcement officers, I prefer to shoot them like they will be fired in different types of CQB situations. So I do not test fire combat handguns like they were target pistols by shooting slowly at traditional bulls-eye targets. Instead, I engage man-size police qualification targets or steel plates shooting double-taps, rapid fire drills, and head shots to simulate engaging an active shooter who is wearing body armor. I also shoot strings of fire from different distances and different angles while executing combat reloading drills.
The XD Sub-Compact pistols scored well in my CQB drills. I had no problem using the 9mm XD Sub-Compact to consistently engage a steel plate the same size as the scoring area of a TQ19 Police Qualification Target at various distances, including at longer ranges. The short stroke of the super smooth striker-fired XD trigger helped me produce a lot of pings and dings on the metal.
The day before I finished this article I fired another 40 rounds of 124-grain 9mm Winchester FMJ ammunition as well as some of the new 135-grain standard velocity Hornady Critical Duty ammunition at an IPSC Target from distances of 15 and 20 feet. I emptied two 10-round magazines and one high-capacity extended magazine into the torso area of the target. I then test fired the 9mm 135-grain Hornady Critical Duty ammunition. I found it to be noticeably soft shooting and very accurate.
