Gentlemen,
I got it from the source when I went to the Glock Armorer's School in May.
I have yet to see one break myself but Glock say's "Rack the slide, do not use the slide stop lever. B/C it will break"
There words not mine I'm just trying to pass the info along.
TS,
I'm a huge HK fan myself but I can't carry one at work. So I only have a P7M8. If things work out maybe I will be able to carry one soon.
