It sounds like an informational purpose to me.
I was wondering about GLOCK pistols and bought the 2002 magazine about them.
I still can't fathom getting one.
I've shot them and handled them, but, my preference is the Beretta 96. The Beretta fits my hand better and I like the design, plus the ability to 'second strike' the ammo in the chamber.
Somewhere I read an article about ammuntion problems with GLOCK pistols, I think it was the CCI Gold Dot ammo, and the comment was made, without directly naming GLOCK, that the ammo was changed to work with one pistol in particular that had an "unsupported chamber"...
I'd like to know if the GLOCK may have been the MYSTERY PISTOL that this article was referring to.
Never know unless you ask.
