They sell them a Glock and send them on off
I have watched as people selling firearms in many stores around here sell them Glocks and send them off.
Many are people who have never handled any type of handgun before. I have heard them asking what is a good handgun for me to buy to defend myself. The answer I keep hearing is the police carry Glocks so I think a Glock would be the right choice for you.
Then they pull out some Glock and say here it is. The people look at it and say ok I will take it then the paper work is done and they ask the buyer if they need Ammo.
They sack up the Glock and Ammo. and send them off not one word about how to handle the glock.
IMHO anyone who just sells a Glock to a person who has no idea how this handgun works. Gives them not a word of advice. Is just sending them off to get hurt killed or some one else hurt or killed.
