I never actuate the slide release on an empty chamber because I think of it as unnecessary wear on the gun. I guess it's the same as slamming your car door closed as hard as you can. What for?
Although, I will say that on my P226, with the .22LR conversion kit, when loading a fresh mag, I lock the slide back and hit the slide release to chamber the top round. The slingshot method, more often than not, results in a FTF.
I wouldn't fire a round without a magazine loaded, unless in an emergency, strictly because of the velocity the slide would be traveling at when returning to battery.
