Tony C,
I absolutely stand by my post.
I also absolutely believe in the right to keep and bear arms, lest I be misunderstood.
Still, it is hard to think of a legitimate reason for the Glock, except for crooked cops to blame it on the gun.
I happened to be in Phoenix ca. 1990 when a cop stopped a teenager for speeding and trying to outrun him. When he finally pulled the kid over, he held his glock with one hand and shook the kid with the other. The gun went off, not from IT being shaken (it's nearly perfect mechanically) but from the cop's shaking. The kid was shot between the eyes and killed. Of course the cop went scot free, although the state paid a settlement to the parents.
An FBI agent, a private citizen, or whoever would be a fool to carry such a weapon concealed on his person. The trigger could get caught on clothing and pulled enough to fire. Even reaching for it could fire it.
Cops, of course, carry it in an external holster where safety is not a concern FOR THEM. It's easy to draw that way while keeping the finger off the trigger, but even if it fires, it's pointed away.
I personally suggest that everyone learn to recognize a Glock, and ABSOLUTELY do not argue with anyone pointing one at you. He may accidentally sqeeze the trigger. Wait until he lowers it to "say anything back". Simply think of it as trying to calm an angry bear. Unfortunately, many guns used by airport guards are Glocks.
