A lot of it is due to, in no particular order:
1. Number of guns in use. Glock has, what almost 50% of the LEO market? Thats a lot of guns out there, in the hands of people who are not necessarily gunnies. Meaning, they don't always get cleaned, the ammo doesn't always get rotated, and the training of the operators can be somewhat lackluster. Anytime you have that many guns of one category, it will tend to inflate the perceived failure rate (as opposed to the actual failure rate).
2. The guns out there in LEO use are shot a lot more than
most guns in non-LEO use. Yes, yes,
we all have guns that we shoot more than the average LEO shoots his gun, but as TFL/THR members we are, lets face it, a statistical aberration. And we all have a safe queen or two, anyway. My point is that a glock that is shot (as a LEO's gun is, at least several times per year), will almost certainly have more failures than a Hi-Point or Jennings that sits in a safe.
3. LEO gun failures are
almost always reported. They either happen in training or in the line of duty (
), and as such the department will be on the phone to Glock ASAP. If they happen off duty, on your own time, you're still gonna contact your department armorer because you either 1. Just blew up several hundred dollars worth of department property or 2. at least want to make sure your duty sidearm gets whatever is wrong with it fixed. Contrast this with Cooter and Bubba going out and running overly warm reloads through their 1911s and sending a slide into the stratosphere. Are they gonna tell anyone? Maybe. Maybe not.
4. Anyone whose marketing includes the term 'perfection' is fairly begging to be taken down a notch or three.
5. The Acolytes of the Church of Glock can be really annoying. This can motivate others to keep the discussion on glock failures going far in excess of what the actual numbers would dictate.
6. Real problems with chamber support, frame rails, etc.
7. People running hot and/or lead reloads through their glocks, and then trumpeting the resultant explosion.

PS Full disclosure- I own one Glock (G20), and I like it OK, I guess. I have no plans to buy any more.
