I disagree. The high number of accidental discharges experienced in Glocks (which you haven't refuted) compared to other manufacturers' weapons with and without external safeties indicate a design or manufacturing defect.
Most all accidental discharges are really negligent discharges. People lie when they do stupid things like firing a gun in the house or blowing their wiener off. They say the gun went “off” when they really pulled the trigger.
The only problems Glocks have are stupid people not keeping their booger hook off of the trigger. Revolvers have the same problem but only Glocks are slammed because of their popularity.
Gun safety is between the ears not a little metal switch.
What in the heck are you talking about? First it was “misfires” now it’s “accidental discharges.” Two different animals. Back it up with facts. Show me the stats of Glocks firing without the trigger being pulled. And there is nothing accidental about a discharge. Keep it holstered until ready to fire and point downrange or into a bucket of sand before pulling the trigger for disassembly. Pretty simple. If it fires when chambering a round or does not fire when the trigger is pulled, then we can talk about misfires.
Do you have to treat them differently than a Beretta 92? Yes. A revolver? Yes. Is it a design problem if a gang-banger goes to a club with it shoved in his waistband and shoots himself in the thigh? No.
I’ve owned a LOT of different handguns, but carry the Glock as my CCW. I want something that is ready to fire when it comes out of the holster and has a light trigger pull. Glock gives me that.
