Glocks were first and highest profile, but the same principles apply to most striker fired pistols.
AD's happen. They have and will happen with everything that is, was, or will be used. Happened with revolvers, happened with flintlocks, will happen in the future with 40 watt plasma rifles.
Specific Glock factors : The black plastic container the pistol comes in from the factory is implied by Glock, and generally considered to be a suitable container in which to store said pistol. The plastic prong intended to go thru the trigger gaurd requires the trigger to be pulled first. By shear odds of numbers, there will be pistols with a round still in the chamber having the trigger pulled in order to put it away. Likewise needing to pull the trigger to disassemble ( not unique to Glock ) . These types of "administrative AD's" will be recorded in the stastics of large LE agencies.
The "on the street" AD's caused by startle, sympathetic hand tightening, wrong pressure points being impacted, etc are probably not signifigently differnt from striker fired semis generally. The same factors occur with the use of DA revolvers, and have also resulted in ADs with them. Could hairs be split and say that X% of instances resulted in having an unintended finger movement of .xy of an inch with 9lb of force , that would not have fired with a DA revolver which would have needed (.xy times 2) movement with 11lb of force ? You could probably cherry pick a couple, but generally a sympathetic movement, or one triggered by nerve impact would have the whole hand clench with considerable force.
You could say by strickly percentages, that ADs increased both with MPD locally, and nationwide generally after the transition from DA revolvers to Glocks ( and striker guns generally) , but the numbers still round to *very few* with either.
Howard County PD has had two AD's from going to takedown the gun for cleaning. Personally I don't care for that design but the solution is simple. Check it. EVERYTIME.
