You know after 20 + years of using Glock pistols, and participating in (usually Glock) internet gun forums I really do get sick ’n tired of reading the same pseudotechnical Glock advertising crapola over and over again. So, for the record: THERE IS ONLY ONE PRINCIPAL MECHANICAL SAFETY ON EVERY FACTORY-STOCK GLOCK PISTOL—ONLY ONE!
Here is the reason why:
Glock's so-called, ‘drop safety’ is NOT a drop safety in the conventional sense of the expression.
The drop safety wings on a Glock’s trigger bar perform one, and only one, essential function: They prevent the trigger bar's cruciform from slipping behind the striker’s lug into a position where the cruciform's, ‘sear tab’ would be unable to engage the lug AFTER the pistol has received a hard impact from, say, a heavy drop or a fall.
There is only ONE PRINCIPAL SAFETY on every unmodified Glock pistol. It is that little lever in the middle of the trigger's face. Never, under any circumstances, should that lever be in anything less than perfect working order.
‘Why’? Because without it, sufficient vibration can be passed to the striker in order to allow it to bypass the striker safety, and fire the pistol. That little trigger lever is actually the, ‘physical anchor’ that supports the other mechanical safety on every Glock—Which is the secondary striker safety, itself.
All Glock's so-called, ‘drop safety’ does is to allow the user to continue to fire his Glock pistol AFTER it has actually been dropped. As several government sponsored tests have amply demonstrated: It will NOT prevent a Glock pistol from firing when it is dropped. THIS is all that Glock’s so-called ‘drop safety’ does, and nothing more.
You’re close - I also don’t view Glock’s “3 safeties” as 3 independent safeties but really three components that must work in conjunction with each other to make the gun safe.
The trigger safety alone cannot make the gun safe. The trigger safety prevents the bar from moving rearward and potentially disengagement of the firing pin safety and the drop safety.
However, because of the way the firing pin safety spring functions on a Glock, a drop could still result in a discharge even with the trigger safety engaged - EXCEPT for the drop safety.
And as we know, the drop safety and firing pin safety could disengage except for the trigger safety.
I was really shocked the first time I met the Full Conceal designer and saw there was no trigger safety. When he said it wasn’t critical I nearly lost it. Unfortunately, there are a lot of people who don’t recognize how critical the trigger safety really is. They underestimate what that little piece of plastic does.
I completely agree with you that the trigger safety is probably the most important of the three but it is not the only safety because it’s not enough by itself.
Yes! That is exactly why I said: 'There is only one PRINCIPAL mechanical safety on a factory-stock Glock.' You are, of course, correct; and you've stated the actual operating condition of a Glock pistol very nicely. We are in agreement. Furthermore, I think it is genuinely important to know how your EDC Glock really works because this sort of correct knowledge can actually prevent a mishap from taking place, and (maybe even) be a lifesaver!
