Help with Glock auto sear

07/02 here and I bought three Glock no demo letter auto sears from Gunbroker. They are the selectable type where you have the option for semi or full auto.
Host gun is a gen 3 G17. Installed the sear correctly in the slide and cut the notch in the rear of the frame. Slide wouldn't close all the way. Worked it for awhile and got a bit forceful but nothing over the top. Eventually it started closing correctly. Problem is the semi auto mode doesn't work. Striker drops. Confirmed with test fire, full auto in both modes.
Tried a second auto sear, identical to the first one, in a gen 4 G17. Installed and cut notch in frame. Will not run full auto, only fires semi in each mode.
Here is a Gunbroker link to the type of sear: https://www.gunbroker.com/item/846285204 Not the one I purchased but identical in design and was made by "Third Pin Industries" who seems to have zero internet presence.
Any ideas or advice to get these running properly would be appreciated. Was rather hoping they would drop in and function correctly in a variety of Glocks.
