I hope JT won't mind, as a curious scientist and statistician, if I ask: What do you believe the reason(s) is(are) for Glocks having an elevated negligent discharge rate relative to other handguns?
I am no expert. Especially when it comes to Glocks, being that I have only had this one for less than a month and only shot it one time. But my guess would be the lack of some type of external safety. With a round in the chamber all that it needed is to pull the trigger for the gun to go off. Even though Glocks have a "safety" built into the trigger, it seems to me that it would not be that hard for the trigger to be set off. I have also heard people blaming Serpa holsters. I have no experience with Serpa holsters so I can't comment on that.
I find myself liking the grip safety on my Springfield more and more. You can't pull the trigger without the grip safety engaged, and you can't even rack the slide without the grip safety engaged.
I like the simplicity of the Glock. How easy it is to field strip. It fits my hand and my wife's hand nicely (she loves the finger grooves). We just don't like the recoil. If I were to have another Glock it would be the G19 9mm. I do like the 40S&W round itself. In a heavier gun, like my P-06, recoil is manageable.
