Bwahahaha! Good one! Competition has nothing to do with combat conditions. You drag your IPSC race gun through the mud, dirt, and water for two weeks and we'll see how well it functions. We'll see how well it groups after you fire through a squib round. Some of the current generations of combat pistols can do all this and still turn in fine accuracy and superb reliability. And when you get right down to it, the skills I see used in competition are frequently directly at odds with the skills used for real combat shooting; people shoot to win the match according to the rules, not to stay alive and accomplish an objective. Even IDPA and nominally "realistic" type matches have this problem (also known as "dojo syndrome").
Among the reasons the M1911 was dropped as an officially supported military arm (though many armories still have a few tucked away -- ours did) was that the military updated their performance standards to reflect the improved capabilities of more recent firearms. Among the biggest shortcomings in testing for the 1911 is the Mean Rounds Between Failures, where it falls well below the current standard and far below the current crop of combat pistols. This shouldn't be surprising and religious zealotry over it is pointless; a LOT of incremental improvements in pistols have been made since the M1911 platform was introduced in 1905. I am not a "1911-hater", as I actually like the way they shoot and am somewhat biased for single-action pistols, but I think it makes for a mediocre combat pistol given the choices available. These days I'd rather have a P220 than a M1911 if it came down to a single-stack .45 with a fine trigger and accuracy, so I don't have a 1911 any more. A pistol is a tool, not a religion.
The only way competition can duplicate combat conditions is if someone was shooting back. The only problem with dismissing competitions is that it's the ultimate in practice. There is no better way to practice than to get into competition. The guns have to work, the ammo can't fail, and the shooter has to adapt to different scenarios that they don't have any control over.
For anyone who tries to practice on their own: Did you practice shooting from a "flat on your back" position lately? Shooting from barricades? Behind cars? Seated at a table? Shooting moving targets? Were you out there when it's 40 degrees with a 20 mile an hour wind gusts. 110 degrees? Weak hand? One handed?
Competition can't duplicate warfare. Competition is more practice and it allows you to grade your practice.
