I would be concerned if a defensive gun choked every 600 rounds.
The reliability question is valid. I dont think the real question would be "all glocks only run some percentage of the time", but that some guns dont work all the time. The common forum comments about "MY gun has run flawlessly for 600 rounds over the past 4 years" as if thats a statistically relevent event dont really add much. (one gun that had repeated problems is more relevent I think) One gun, and that small a number of rounds is a drop in the bucket. Some people will shoot 3 times that much in a weekend class, and some people simply shoot WAY more than others.
Glock do in fact have some known, occasional quirks that sometimes are fixable, and sometimes glock cant even make them run right. Thats just life.
I notice when people comment about several hundred guns their department uses and had X number of certain problems in X number of average rounds through them.
