I hate Deagles, but I know they’re a hoot to shoot.
I don’t own a Glock, but I know they’re a good gun to start with.
I know Glocks are good guns to start with, but I wouldn’t recommend one to someone whose hands have been weakened by arthritis or age.
Context matters. There is no “one size fits all” solution for sodas, (that’s why they make Pepsi, Coke and RC) and there’s no perfect carry gun for everyone, everywhere. There are reasons why maroons like myself prefer Macs over Windows, why people use Linux over Macs and why people choose something other than a Glock 19 for their first gun. Some of them might be bad reasons (dumb advice from gun store clerks or supposedly knowledgable friends), some might be good reasons, such as it was for me, when I found I was demonstrably more accurate with a CZ75 starting out than I was with a Glock 17.
Chesterson’s fence applies to a lot of things, and the gun community would be a better place if we heeded its lesson more often.
