As someone who has been shooting handguns for 50-plus years, I think it's amusing to observe shooting fads. These run in cycles.
When I first came up in shooting, the long-range use of the cavalry pistol in the Civil War era was a distant memory. Pistol shooting was a close-in defensive activity for the military or police, or, rarely, the civilian defense shooter; the handgun viewed as the equivalent to a battle-axe, useful only at very close ranges.
In the 50's and 60's, the writings of Keith and Skelton and others woke us up to the potential of the big sixgun in hunting, to sometimes extended ranges, but defense handgunning was still an arms' length proposition. The PPC police pistol course had only a few rounds at 50 yards. PPC matches were limited invariably to police and security personnel. The Big Bear Leatherslap, and later IPSC and IDPA, emphasized quick shooting at quite moderate ranges. The fast draw craze of the late 50's and 60's emphasized shooting at ZERO range, with blanks!
In the 70's, the hunting handgun became a sport pistol, and the silhouette game proved that a good sixgun or single shot could hold sub-3moa grouping to extreme ranges. Defense practice with autos still was hampered by their generally inferior accuracy, with most big frame service autos being incapable of better than 12-20 moa accuracy. It's the popularity of these latter 'crunchentickers' for IPSA, IDPA and such-like pseudo-combat games that has once more relegated the pistol in most user's minds to the 'close combat' role. Of course, some target autos approach a revolver's OOB accuracy, at the expense of inferior reliability.
A good sixgun or single shot is a useful tool to very extended ranges...with practice, and good ammunition. Many 'combat' shooters too would find their military and defense style autos surprising, if they practiced with them to longer ranges. I have to laugh when I read of some guy who thinks his new SigHKCz .401 Slapshot is a great gun because he gets 7-inch groups at ten yards. It has a lot more potential than that, as some astute owners have already learned.

If they take our guns, I intend to let my hair grow long and acquire the jawbone of an ass.
