That's not "spray and pray".
Do you even know what "spray and pray" means?
I have yet to run across a case study that called for a double-column magazine in a .45 pistol. The highest score I know of in a gunfight was five, which was achieved by a shooter using a single-column magazine of 7-round capacity. It would seem obvious that the “spray-and-pray” method we see in gunfights is both ineffective and ridiculous. According to doctrine we shoot twice (except for head shots), and this is just to take care of unforeseen errors. There is nothing wrong with having a whole lot of rounds available in one loading unless it actually reduces the efficiency of the weapon, in which case the idea should be dropped. The double-column magazine, in a major caliber pistol, does indeed reduce efficiency and affords nothing particular in return.
There is also a worldwide preoccupation with fully automatic, hand-held fire. The “spray-and-pray” concept may be held in contempt by sophisticated shooters throughout the world, but there are not many of those. Most people in the press and law enforcement seem to feel that a whole lot of shots, hit or miss, is preferable to one well-placed hit. We cognoscenti know better than that, but we are in the minority.
