I've had and carried for 15 years a 92 Beretta, shooting a lot (more than 20.000 round / year).
The tecnical life for a 92 model is about 3.500 rounds (....just a few...!).
Glock is now my favourite gun (19C model) and I had it since 2000 year. I now own the 5th.
I've used it at the same rithm, changing just the firing pin spring and the disconnector spring. The first one weacks in 1 year of carryng in condition 1, the second breacks in 15.000 rounds.
No other problems with glock: I fired a round also in a swimming pool, 1 meter depht
I believe he means to say an average service life of 35,000 rounds. However, I don't know about the Italian military, but the U.S. military has many, many, M9's still in service well past 35,000 rounds. The M9 has been in U.S. service for the past 25 years and has seen numerous theatres in war(unlike Italy or Austria), perhaps more than any pistol on earth, has been handled, shot and abused by troops who are known not to be the best at maitenance and don't own them.. I do believe 25 years in U.S. service and many wars are a testament to the M9's duarability,longevity, and reliability, as the M9 is destined to go down like it's predecessor the venerable Colt 1911 as a true and abused war horse, when and if it's replaced. Beretta USA announced on September 30, 2011 that the U.S. Army's Foreign Military Sales program has purchased an additional 15,778 Model 92FS pistols for the Afghan military and other U.S. allies. The Model 92FS is the non-U.S. military designation for the M9 pistol. In September 2012, Beretta USA announced that the US Army had bought 100,000 M9 pistols and that the M9 "would remain their sidearm for the next five years."
