Before someone chimes in with: "But a Glock has three (3) safeties!" let me be the first to point out:
The truth is that Glock’s so-called, ‘three safeties’ thing is all advertising bullhooey. Anyone who is genuinely familiar with Glock’s basic design already knows better!
The fact is that Glock pistols have only one primary safety—ONE, not three! (And Glock's ONE safety is that lever-actuated, mechanically applied and compulsory, safety lever that every Glock shooter MUST use every time the trigger is pressed.)
The, ‘striker safety’ itself is an integrated, mechanically applied, ancillary safety device that functions in addition to—but not independently of—a Glock trigger’s primary safety lever. Glock’s so-called, ‘striker safety’ can NOT be relied upon to function independently; and, ideally, it MUST be used in conjunction with the primary trigger safety lever.
Furthermore, not only is Glock’s so-called ‘striker safety’ incapable of independent operation, but, it can also be overridden by both physical impact, vibration, and/or rotational force.
As the Glock factory, itself, has warned for many years: Never remove the trigger (safety) lever from any Glock pistol. ‘Why?’ Because if the lever is removed then Glock’s, basic, closely integrated, trigger safety mechanism will become highly unstable; and very unsafe to carry or use.
THE TRIGGER SAFETY LEVER, ITSELF, IS EVERY GLOCK PISTOL’S PRIMARY AND MOST EFFECTIVE SAFETY DEVICE.
As if this isn’t already enough, by any conventional understanding of the term, Glock’s so-called, ‘drop safety’ is not actually a drop safety, at all. Instead it’s a mechanically applied, anti-binding device that—sometimes and under certain conditions—MIGHT act as a non-discretionary ancillary safety.
The main purpose of Glock’s so-called, ‘drop safety’ is to prevent the trigger bar’s, ‘sear tab’ from becoming locked up in back of the striker lug—Which would cause an unexpectedly dropped Glock pistol to suddenly become incapable of firing! (NOT a good thing to have happen!)
EVERY GLOCK PISTOL THAT HASN’T BEEN MODIFIED FROM ITS ORIGINAL DESIGN HAS, EXACTLY ONE PRIMARY, NON-DISCRETIONARY, MECHANICAL SAFETY; AND IT’S THAT LEVER ON EVERY GLOCK’S TRIGGER WHICH THE FACTORY HAS REPEATEDLY WARNED SHOULD NEVER BE REMOVED.
Now you know, ‘Why’. THAT LEVER on every Glock pistol’s trigger IS GLOCK’S PRIMARY, INTEGRAL, AND NON-DISCRETIONARY, SINGLE MECHANICAL SAFETY. Without that lever Glock’s entire, closely integrated, safety mechanism will become highly unstable and can easily fail.
A Glock has one safety which is the articulated trigger (the lever inside the trigger), but it doesn’t surprise me that the recent buyers don’t understand that. Anyway if the report is true, there might be a lot of good deals out there, on used guns.
