Dry firing is still common advice, as is verifying the condition of the gun and the 4 rules of gun safety.

A lot of Cops probably dry fire their Glocks and similar handguns while taking them down for cleaning more than they do pulling the trigger on live ammo. I always hated having to do that with my own pistols. I'd be willing to bet money a number of negligent/accidental discharges have resulted from expecting a "click" and getting a "BANG!" instead.
Only time I dry fire now is pointed downrange at the range. Occasionally with a revolver I'll leave a chamber empty to check for flinching and steadiness of trigger pull/hold on my part when the hammer lands on that random empty chamber.
