Oh please, Glocks are just about the most reliable handguns on the market - they go BANG every time you pull the trigger, and they have survived every torture test you can imagine.
And I am not a Glock owner, BTW. The only reason I don't own a Glock is that it's not as comfortable in my hand as the SIG that I do own, another gun that ranks right at the top in the total reliability column.
Any gun will go Ka Boom if someone who doesn't know what the hell he's doing tinkers with it, or if you use super hot ammunition that exceeds the maximum pressure the gun can handle.
I've done a little research on that and I would agree.
I'm not a pistol person, I've had rifles around all my life but
never any handguns. I started firing Eaker's Glock and did so for
a few years, while also firing Sigs and S&Ws and others.
At the end of the story, I bought myself a Glock 27 because
I liked it the best and I was impressed with the quality.
I still can't find the safety though.
