- "They gave Tomás a gun. Gave him a choice. Him or some dude. So he did it. Told me all about it like it was nothing."
"Who did he say he killed?"
"Some dealer. From some outside crew. Right around the corner from here, over off of Central. Just rode up on his bike and shot him."
"Off of Central? Like over by the train tracks? When was this?"
"Few months back."
"What else did he tell you?"
"He shot the guy right through the neck. Shot him dead. Just because he was working the wrong corner. It won't happen again. Not to my son."
- ―Andrea Cantillo and Jesse Pinkman
The Glock 17 is a 9mm short recoil-operated locked breech semi-automatic pistol that uses a modified Browning cam-lock system adapted from the Hi-Power pistol. The firearm's locking mechanism utilizes a linkless, vertically tilting barrel with a rectangular breech that locks into the ejection port cut-out in the slide. During the recoil stroke, the barrel moves rearward initially locked together with the slide approximately 3 mm (0.12 in) until the bullet leaves the barrel and chamber pressure drops to a safe level.
A Glock 17 is carried by police officers in Live Free or Die. In Madrigal, Chris Mara uses one with a supressor to kill Duane Chow. A Glock 17 (accidentally instead of a 22), is used by Hank Schrader during the gunfight with Jack Welker and his gang.
Later, after Neil is killed in a duel with Jesse, Casey grabs the Glock from his trousers and shoots at him, engaging a brief duel with Jesse. Casey misses while Jesse is able to hit Casey in the head with Neil's gun and kill him. Unlike the other weapons used in the gun battle, Jesse does not appear to take the Glock with him and instead leaves it to be destroyed when he blows up the welding shop. ("")
