Out of the ten groups, I had two, admittedly firing laser and not bullets, that had a spread of less than one-third of an inch. After only minor adjustment to the sights, these two groups had both fallen with all five shots in the ten ring (or having broken the line) with the center of the shot-group also within the ten ring. I noted that the two groups were just a little high and to the left on the target, but since they still all fell in the ten ring I dismissed the minor discrepancy in relationship between point of aim and point of impact. I felt that if I could achieve this kind of accuracy on the range, I'd be doing pretty darn well. Off to the range I went.
Way back when I first got the pistol, range day was warm and cloudy with the occasional breeze to relieve the almost ninety degree temperature. I posted a couple of bullseye targets, loaded up my magazines with ten rounds of Winchester 115g FMJ ammo and proceeded to shoot five shot groups. Firing free hand from the fifteen yard (45 feet) line, just like with the laser zero, all groups were a little high and left, though the "little" was much more noticeable with real bullets. Still, my best group spread was one and three eighths of an inch: four shots in the nine ring, and one in the eight. The worst group I shot measured two and a half inches with three in the nine ring and two in the eight. As noted, all groups were just a little high and to the left. More recently, just a few days ago, it was a cooler day and was just drying out after several days of rain. Obviously, weather has a greater impact on the shooter than on the weapon, but the accuracy of the weapon hadn't changed. This was a different pistol - obviously - but same make and model and same standard of performance.
The weapon functioned without flaw. I had cleaned it and lubed it in accordance with the maintenance manual. No feeding malfunctions, ejection malfunctions or failure to fire occurred. Just to make sure it wasn't because of the nicely rounded FMJ ammunition, I pulled out some old Federal Hydra-Shok 124g JHP +P ammo that I had in the bottom of my ammo can. The SigPro ate through three magazines of the Hydra-Shok without any problems. Rapid fire five-shot groups from the seven yard line averaged less than two inches and noticed recoil was minimal even with the hotter load of the +P rounds.
All in all, the SigPro 2009 is a handy weapon. Not so large as to be inconvenient off duty and light enough to help out weight control on the gunbelt on duty. Accuracy is certainly not an issue as I had a feeling the gun was better than I was. With fifteen rounds of 9mm per magazine, ammo capacity is sufficient for law enforcement work.
