If it really only costs GLOCK $75 to make a G17, when all expenses, etc., were covered, why don't they charge dealers $150, and have dealers in turn charge consumers $300? Everyone would be netting a 100-percent profit, it would be the cheapest high-quality gun on the market by a long shot (cheaper than a basic Taurus .38), and their sales would skyrocket. Needless to say, in real terms, taking into account industrial plant, overhead, liability, and so on, it costs them more than $75 to make a pistol. Certainly they are a healthy and profitable company but I doubt they are netting 4-5 times their total investment per unit.
For sure Gaston Glock intended to make a pistol that would be competitive in the marketplace, but I doubt his "sole intent" was to be the lowest bidder in an absolute sense. Perhaps the lowest bidder on a gun that was otherwise comparable to designs by Sig-Sauer, Walther, Steyr, HK, and so on, in terms of accuracy, durability, reliability, safety, ease of maintenance, etc. But I suppose you could say that about any manufacturer who tries to secure contracts with agencies, departments, armed forces, etc. Do you suppose that when, say, the FBI or Coast Guard solicits bids for new sidearms, the HK rep calls up and says, "Well, we're not gonna be anywhere close to the lowest bid, in fact you could buy 4 or 5 G22s for each P2000, but let me tell ya, it'll totally be worth it!"?
