It's not as if I wait until they start malfunctioning to clean them. They just haven't malfunctioned, so I'm content and comfortable with the six-month cleaning schedule.
Chuck Taylor has mentioned he has a Glock 17 that has gone 20,000 round between cleanings, and it's still going strong at over 175,000 rounds. Even the ever-cautious Massad Ayoob has stated flatly that he'll sometimes let his Glock 22 go several thousand rounds without a cleaning.
