My point is Glocks are consistent and uniform, and entirely usable right out of the box. They are also very cost effective at around half the price of 1911's and Sigs.
Toyota Corollas are consistent, uniform, and entirely useable in stock form. I wouldn't settle for one though.
When boiled down, your sole Glock "advantage" is only such if it is in one's nature to be a cheapskate as it has been amply pointed out that many pistol series come in virtually identical models in a array of calibers.
