well having worked at two different gun plants, fitting building and test firing at them and visiting, for a few days each , two others, all of this in the building ,fitting and service ends of it including test firing, ENOUGH people handle, look at and then FINALLY get a once over before shipping, ( and even they, in shipping ,both men and women, ) happen to look at , roll them over, and gave them a cursory inspection.....all too often things would be "picked up and out" pulled off the line, sent back to be recycled, gone over,,,and I can tell you , PLUM finishes, missing chambers, out of time spitting lead, or failing to lock up ( go click, click) were NOT accepted, they did not get shipped out, even accuracy came into play, some are proof tested and then shot for accuracy, using two different types of ammo ( Dan Wesson and High Standard) and this sort of thing just usually did not happen......as 'splitz ' alluded to, these "parts" are done aforehand, parts are inspected coming in, and in the hands of ANY fitter, looked at during the built, I can honestly say almost EVER builder, fitter that I worked with, knew in a nano second if any given part was good or bad , before they even tried to use it........sorry , NO excuse...today they are just in TOO much of a hurry to "get it out the door" and pre testing, is something out of the past?????
gee, just think if Boeing did it this way.......Yikes!! :shock:
