I could post a photo, but it only mentions the slide stop 4 times in the manual for Gun Inspection, Clearing Misfires, Unloading and field stripping. All 4 times it just says the same thing:

"Pull the slide fully to the rear, press upward on the slide stop while letting the slide move slightly forward thereby locking the slide open."

Other than that, for loading you pull the slide back and release it as stated in my earlier post
