We used Glock 19's in Iraq. They were Jam-o-matics. Regardless what you heard, the fine dusty sand jams the living &*&&^& out of them. The military's Berretta 92 were almost flawless. The Berrettas were just nonstop reliable.
Unintentional discharges were not uncommon when trying to holster a Glock while wearing a pack. The index finger would be pushed onto the trigger inside the trigger guard by the Glock holsters and a discharge would result. The pack prevented us from seeing the holster many times.
I did not trust the glocks and well as many on my team.
The Second Amendment is a doomsday provision, one designed for those exceptionally rare circumstances where all other rights have failed -- where the government refuses to stand for reelection and silences those who protest; where courts have lost the courage to oppose, or can find no one to enforce their decrees. However improbable these contingencies may seem today, facing them unprepared is a mistake a free people get to make only once." -- Justice Alex Kozinski, US 9th Circuit Court, 2003
