I cannot really be surprised. Collectors are strange birds indeed as I’ve witnessed on this forum! You can have two identical vintage S&W revolvers save for a different dash number or some unique stamping which can cause a flurry of lengthy responses, in-depth conversations, pages upon pages of discussions, sharing of information and a ridiculous monumental increase in value!!!
Many collectors on this forum enjoy the detective work or should I say comprehensive in depth forensic examination on every minute detail of the gun in question! To some, this causes a thrill up their leg like a former CNN host! To others, it’s similar to watching grass grow!
An original Glock 17 and all its accouterments is somewhat of a rare bird these days, greatly desired by Glock collectors including the magazine which as mentioned here, was different than later Glock 17 mags.
Of course this Glock thread wouldn’t be complete without the usual Glock bashing, and sure as the sun rises and sets, the detractors cannot resist and must offer their two cents! I then think about Chuck Taylor's G17 Gen 2 torture test was up to 365,000 rounds in an article dated 14 September 2017, and I believe it went well past 500,000. Many of the detractors favored handgun would be in the scrap heap long before this!
Anyhow, I find it surprising that forum members are surprised by an expensive rare Glock 17 Gen 1 magazine? Have “you people” looked at yourselves lately!?
