In rifle work group size is of some interest, but it is by no means the critical consideration that some commentators seem to deem it. It is well to remember that a rifleman does not shoot groups, he shoots shots. A tight group is nice, but one must not fall into the error of PII (Preoccupation with Inconsequential Increments). I have shot a great deal in a long shooting life, and I have only once encountered a rifle that would not shoot better than I could shoot it. (That was a 32-20 lever gun which had been allowed to rust and then scraped out. In getting the rust out of the barrel, most of the rifling went along with it.)I am sorry to say that this nugget of cantankerous cogitation is cute but dumb. Three years ago, its daft but pervasive notion of a gun that shoots better than the shooter inspired me to write this post. To summarize its argument, any mechanical looseness built into your handgun in order to ensure its reliable operation, compounds your errors of aiming, shooting, and following through. Any additional degree of slop caused by stacking production tolerances will degrade your shooting performance, regardless of its level.
Group size is unimportant, unless it is very bad. If you can hit a dinner plate, first shot, every time, under all conditions, at 100, that will do.
Furthermore, imperious imputations of unimportance to this or that aspect of our avocation, are both unapt and un-American, even when announced by anointed authorities. It may please you to “hit a dinner plate, first shot, every time, under all conditions, at 100”; but that has nothing to do with realizing my interest in doing likewise to a barn door or a silver dollar. We live in a free country, where it behooves everyone to formulate his own goals in the pursuit of happiness, and everyone else, to stay out of his way, inasmuch as he reciprocates in kind.
Lastly, in the issue at hand, the consequential increment relates not to accuracy, but to ruggedness and durability. I have some remarkably accurate guns, which include two of my favorite centerfire target pistols, the long-barreled W+F 06/29 Swiss Lugers from the 40 pistol Swiss National Match production run for the 1949 ISSF competition in Buenos Aires, won by Heinrich Keller, as discussed in my article linked above and shown in the photo reproduced below. Korth revolvers are not dedicated target guns that distinguish themselves along the same lines. They are optimized for other qualities, which may or may not serve your interests in shooting. Don’t rely on reviewers. Find out what’s important for you, and do as you see fit.
