ISB, the intellect in me agrees with your opening statement; my gut has a problem with it, however.
As to IDPA, IPSC, or other 'Gungames', let us consider the facts that support your statement. While any other gun runs in an 'out of the box' condition, an 'out of the box', or modified substantially, 1911 (or other single action aut, I believe), pistol, runs in a higher "racegun" kind of class, separate from the others, with IDPA; with IPSC, 1911 pattern guns are the vast majority, even now.
In IPSC, there is substantial prize money, etc, encouraging taking a risk, for the dollar, with no blood loss eminent!
In IDPA, there's not nearly so much money, but again, it's a 'gun game', and no blood is lost.
It's not unusual to run 200 rounds through a 'game gun', or, even, many more, between cleanings, and the, only a 'field strip'!
My little Colt saw over 1000 rounds, flawlessly, before it went 'into service' as a carry piece, and is never carried with any mag that was not in the proving lot of mags; in this 'game', there is NO prize money, but always the risk of blood loss, and is to be considered differently, IMHO.
Every time it goes to the range, and is fired, it is detail stripped, and cleaned to 'as new' condition. So, when it goes back 'in service', conditions are exactly the same, every time, which is far from the life of most 'game guns'.
While in the military, every time I got back to Ft Bragg, I was detailed to the XVIII Abn Corps, or the 5th Army, pistol team, in the shop(s), or as a 'fill in' shooter, until I shipped back overseas. I suppose it might have something to do with a pistol I reworked for a Sergeant-Major, at the JFKSPECWAR Center, in '69, with which he shot extremely well, until his death; The fact remains, for one who understands the M1911, it is the most reliable pistol ever built.
I shoot the previously mentioned "lightest 5-shot Smith Revolver I can find", left handed, exclusively; for one good reason: I've shot the 1911, in the other hand, for 40 years, and close to 1,100,000 rounds, with my right, successfully, and don't wish to mess with apparent success, in muscle memory!
Your statement is absolutely correct, as I said in the beginning, if I allow these provisions: First, you can live long enough to shoot long enough to arrive at the statistical premise: "Nothing is 100% functional", and Second, that you are allowed to shoot a weapon, of my preparation, beyond reccomended maintainance intervals, and count those results as statistically significant.
Lacking those two provisions, there are at least twenty, and likely many more, smiths than can give to you by these standards, a 100% gun, many at a price even I could afford!
No hard feelings, just excellent guns! Terry
