Never realized that I am supposed to be very unhappy with the slide-to-frame gap at the muzzle end of my G23. The gap isn't evenly spaced all along from back to front. At the front couple of inches, the gap tapers down by half at the front end. Worse, there is a (measured) overbite of .012". And Gaston Glock claims perfection??

But wait. It was born in November of 2004. Although it bears no police department marks, it was represented to be. The left side of the slide at the muzzle end has what is probably holster wear. It is possible the pig snout was formed over many years by pressure from a holster. Hence, the reason it is called used.

I guess I am more fortunate than some, who are upset that their Glock has pig snout brand new, out of the box, and didn't know to look for it, until discussion appeared in an online website.

Meanwhile, I so worry, day and night, that I must pull the trigger to field strip it...
