Animated Explanation of Glock Pistol Function

Very good video, probably the best/most accurate I've seen. A few notes:

1. Some of the parts in the video are aftermarket. The trigger, for example in some views shows an adjustable overtravel stop which is not characteristic of the factory part.

2. The video shows the firing pin still in the fully forward position at the end of rearward slide travel. In reality, in most cases, the abrupt stop as the slide hits the end of rearward travel will cause the firing pin to move back behind the breechface and firing pin safety.

3. This video accurately shows that the slide motion fully resets the trigger before significant compression of the firing pin spring occurs when there is nothing holding the trigger back. Many videos show the trigger resetting and the firing pin spring compressing at the same time. The trigger spring is a lot weaker than the firing pin spring so it loses the battle and the firing pin spring stays mostly uncompressed until the trigger stops moving forward. Of course, in most cases, the shooter's finger is still on the trigger so striker spring compression starts as soon as the trigger bar catches the firing pin lug as the slide comes back forward.

4. Although the video properly shows it, there is no mention of the second function of the connector "cam". That function is to help prevent out-of-battery firing. The cam disconnects the trigger from the connector until the slide is nearly fully into battery.
 
Too bad there are not such detailed videos of every other common carry gun we all own. That would help a lot of people understand how their gun works. From reading many of the posts here a lot of shooter don't have a clue and don't even want to know.
 
Like many of those diagrams I have seen, this one makes a mistake, showing the barrel/slide as being motionless relative to the frame until the bullet leaves the barrel. In fact the barrel/slide unit begins to move back in recoil the instant the bullet begins to move and is moving back while the bullet is moving forward in the barrel. (The barrel/slide unit is heavier than the bullet and takes longer to get up to speed, but it does not wait to move until the bullet is out of the barrel as the diagram shows.)

Best Glock operational video I've seen!!

I wondered about this too. But, what I really wanted to see, and what the video did a very good job with, was just how much the trigger moved the striker when on each trigger pull. More than I thought.

Based on measurements done on a cutaway Glock, the slide preset compression and the trigger compression of the striker spring are roughly equal.
