Because of the way Glock introduced the gen 4, which resulted in a fiasco, a lot of misconceptions have followed.
One is about the gen 4 trigger pull and that is what this series addresses. Some are claiming the gen 4s have a heavier trigger pull than the gen 3s. For a while that was true, but Glock has corrected that just like they corrected a number of other problems with the gen 4.
The following three videos explain how the Glock trigger works and thoroughly addresses the misconceptions about the gen 4 trigger action.
You'll have to forgive parts of the video where things get jumpy. I didn't realize how much I was moving my hands and parts around during the shooting and I wound up chasing my hand motions all over the place in the editor and let some go because it was just taking so much time.
Anyway, take a look, I think you'll find these interesting and informative. Be careful about skipping around in the videos - there are a lot of details covered and you can miss those thinking you've seen it before.
BTW, does anyone know? If I post these as shown below, i.e. video within the thread, and someone watches one, does it increase my YouTube view count? The reason I ask is because I've done this before and I know guys are watching them but my YouTube count doesn't seem to reflect it. If it doesn't, I'm just going to use the links. It's important to me to know if and what videos are being watched.
