I don't want to speak for Vert, but I believe he was just making light of a pretty prolific ".22LR pistol for self defense" poster from a while back.
Sometimes sarcasm is lost in translation. I have fallen victim myself. You are correct, I was poking fun at another very old thread that we still make fun of.
What tool have you used to remove the Glock 44 polymer sight? It looks like there is not enough clearance between the screw and the front of the slide when using the standard Glock sight removal.
Glock rep did not recommend replacing the rear sights. I have not looked closely at the front sight but was led to believe it is the same as other Glocks. Will have to pop one apart and look if I get time.
