I usually rely on personal experience or first hand knowledge. You can google alien abductions and find even more revelations. In I forget how many 9,40,45acp Glock pistols and I would guess conservatively north of 30,000 rounds over 25 years no Glock breakages in my hands or anyone that I know. Odds are better it seems with Glock pins than with a new pistol 4 months old and multiple pin breaks.
