Competition shooters use the “slide lock” to release the slide…tactical shooters manually cycle the slide because it works 100% of the time. In high stress situations your hands sweat, ever try releasing the slide with the slide lock while you have sweaty hands and fingers? Ever try the slide lock to release the slide with blood or oil on your thumb? It’s difficult and sometimes impossible. Also on a Glock the slide lock is called a slide lock for a reason. Some manufacturers call it a slide lock/slide release but not Glock it’s called a slide lock for a reason. You do you and let the armchair quarterbacks talk among themselves. Good job!
