Elvishead's last post brought up the crux of the matter for which there will seldom be any qualified answer except from factory or military testing. That is, the distinction between an individual gun, which may simply be defective, and a design that is inherently imprecise. The reason nobody here can present a qualified answer is our experiences are almost certainly all anecdotal. It seems unlikely that any one of us has owned and shot statistically significant numbers of any one particular model of gun on a personal basis. Perhaps as part of a government or commercial testing program, but not at home on our own. The industrial statistician at my old job would have said 30 samples would be the minimum required for that, and they would have to be samples carefully chosen to ensure they were random, and not a serial set of samples that came off the assembly line in order. I own several 1911's, but no two are identical and none are out-of-box examples, so they don't count for evaluating a particular factory 1911.
Most mass-produced guns have good and bad examples. The Redhawk whose 50 yard group I had in the third photo from left in my second post is an out-of-the-box factory gun except for the trigger job. A friend of mine bought the same model, but his copy would not hold 6" at 25 yards off bags. We returned it to Ruger. They sent it back 5 weeks later with a note stating they had reamed the chambers. Sure enough, it shot dramatically better. Not quite up to mine, but close to it. So, was the gun imprecise? Yes, relative to mine, as it came, it was. Would it still have shot minute of bad guy at 7 yards? Yes, it was nowhere near too imprecise for that. Is the design inherently too imprecise for good accuracy? No, mine proved it is not, since even one exception disproves a rule. Is the manufacturing imprecise? The two revolvers taken together tell us it is less precise on some copies than on others, but what the statistical average result is, I have no idea without randomly sampling at least 30 of them. Which out-of-box level of precision can you expect, on average? Same answer.
First I've read that. Some were not as well made as others, for sure!
