When I read such reports, I try to find at least 10 different reports and then I read between the lines. I never trust entirely what is on the Internet. Nonetheless, when I test out a gun and I do happen to encounter failures, I disclose them since this might help someone make a better decision on which gun to carry and probably help them save their lives.
I have an HK USP Compact that after 3,000 rounds has had only 2 FTE that was ammo related. A Walther P99AS that after 1,000 rounds has had 0 FTF/FTE, a S&W 442 that had problems but was related to lead ammo (forgot to see this in the user manual). All of my other weapons (shotgun, rifles and AR) have been very reliable.
