As a Glock owner (and lover), I was surprised not to see that name in the article. I am not surprised to see it in the comments, and I suspect you are right. Glocks are for people with perfect gun manners, not for cops who specialize in donuts and paperwork.
I assume Glocks are great guns from those who I know and trust who own them. Like any gun they require diligence. They have garnered a certain reputation as not ‘fool’ proof. I have been offered them to try by firearm industry folks. Might just take them up one day. Till then I have my 1911s. My other 1911 style autoloaders and my many double and single action revolvers. That’ll do for now.
