Now this is interesting. This runs counter to the narrative that the old stuff was built better. The folklore is that back in the day you had actual artisans building the guns. This sentiment seems especially prevalent among those who favor old Smith & wessons, like me!
Let's talk about this
Well, you'll note that I excepted S&W's in my discussion of old guns that didn't work. Smiths usually did, and as long as you were OK with a Smith revolver you were usually OK. Autoloaders were notoriously unreliable and that includes Colts. Even if you got lucky enough to get one that worked you always felt like it might not work THIS TIME. I had two brand new Colts that would not fire when they came out of the box. Explanations are too long for here but, bottom line, neither should have left the factory. Colt revolvers weren't necessarily unreliable but the grip frames were so big, especially on the Official Police and New Service guns, that I just couldn't use them. My point with all this was that "the good ol' days" weren't necessarily all that good when it came to handguns, and a lot of the problems I experienced then just haven't happened with the modern plastic pistols. And I don't limit that to Glock. I also have HK's, Canik, SIG and others and they're all utterly reliable. One other point - for years I taught classes with John Farnam. These were high round count classes (1000+ rounds in two days) and very hard on guns. Back when students used 1911's and revolvers we spent inordinate amounts of time fixing guns and trying to keep them running. The only really reliable guns were the surplus military 1911's with hardball, if they hadn't been messed with. The tricked out 1911's were the worst. In the years since the transition to plastic guns those issues have disappeared. Not to say a gun doesn't break now and again but it's nothing like it was 40 years ago. So, as I said above, I don't love Glocks or others but I do appreciate them for their rock solid reliability, and that's what counts first in a true defensive handgun in my book.
