Trouble is, a net increase is more likely, because trigger locks are dangerous.
I make that assertion as a firearms safety instructor, an attorney, and the father of two small children. A trigger lock must be attached to a gun at the trigger, exactly where a finger would go to fire the gun. The lock is supposed to go on an unloaded gun, but if the user has erred and the gun is loaded when the lock is attached, then the gun may be accidentally discharged during the attachment process. It's easy to attach a trigger lock loosely so that it still allows the trigger to be pulled. Trigger locks are easy to defeat if you have a little time.
