OP's question: Are Glock owners the new 1911 people?
No.
Glocks have been around since 1982 ...
The 1911 since ... well, 1911.
Ask again in about 75 years. Besides, 1911 curmudgeons complaining about a new polymer-framed, striker-fired pistol cannot be compared to Glocksters complaining about ... new polymer-framed, striker-fired pistols.
Gun guys are just like truck guys, Jeep or any other four-wheelin' guys, watch guys, guitar guys, cigar guys, Scotch whisky guys, etc ... Everyone has got their chosen platform, make, model, brand, edition, whatever, and they'll be quick to dismiss anything else as inferior. Gun guys are also some of the most opinionated people I know.
Frankly, to me, the folks that spend the most time talking about, defending or promoting their chosen platform are usually the same folks that think it's the tool and not the operator; they don't train, practice or often even understand the legal, moral and ethical obligations of firearm ownership. I could care less about what someone's favorite pistol is, so long as they are safe, train and see the big picture.
