Great question. As long as the firing pin block is mechanically sound, which the design certainly seems to be in a Glock, then I personally wouldn’t and don’t have an issue relying on it. Then again I’ve Gadgeted my carry Glocks and I don’t worry about it. But that’s just me.
Glock’s design is prove and sound. Unless you can show evidence of a particular sample of being broken or unsound, then there is no issue. Carry on and stop worrying.
