This was a great catch. I bought the BG 2.0 a couple days after it came out and I've had that little bit of a hitch with the slide since day 1. I took a look and the roll pin was a skosh to the left so I gave it one quick punch and it smoothed it out 100%There was one off issue with this particular example I will make note of.
In the rear lower roll pin, it was not fully seated through both sides of the frame properly. This created a little tightness in the slides action cause it was just enough out of alignment with the slide rails front and rear that it slowed down the action of the slide. Once I looked into it and realized the pin wasn’t evenly distributed to both sides, correcting it freed everything up and it’s very smooth now. I found and corrected this before I ever fired the gun, it was pretty easy to figure out just cycling the slide for dry fire practice
I also moved the rear sight over just a hair with a slide-pusher because it was off. It seems to be a pretty widespread issue with the sights from what I've seen a ton of the forums.
