Would you mind providing a source that shows that the Glock mags are flawed by design?
I don't know of a source, other then my personal experience with my Model 23 over 12 years.
And about 45 years of gunsmithing all kinds of guns.
Oh!
And the
2004 Glock Annual, published by Harris Publications, for Glock as advertising media. (Free handout at Cabala's)
In it, on page 38, is an article by Chuck Taylor titled
Glock 17 Torture Test - After 13 years and 186,000 rounds, it's still perfect!
On page 41 Taylor states:
"100 rounds short of the 5,000th shot, the magazines failed to lock the slide open."
Later on the same page, he said:
"At 11,000 rounds, another new set of magazines gave up."
On page 42 Taylor states:
"In fact, since discovering that loading 15 rounds instead of 17 into the magazines prevented the springs from softening, and I haven't had a single malfunction since."
Then later he said:
"I replaced the magazine springs with a new set of Glock springs early in the test (11,000) and they are all still functioning perfectly after 100,000 rounds."
To me, that indicates over-compression, and a design flaw.
They designed them that way so they could get 1-4 more rounds in the mag then other guns of the time period.
The contempery Browning HP only held 13, the S&W 59 series held 15, but you can leave them loaded till hell freezes over without hurting the springs in the slightest!
PS: Take a gander at this X-Ray picture of a fully loaded Glock magazine and tell me thats good for the spring!
