If I'm not mistaking some Sig P320 models come without a safety switch. However, one could, you know, not keep a round in the chamber, especially if there is no safety switch... So yeah, the users does carry some of the blame.
In general, handguns with active safety levers are considered less-safe than firearms without active safeties when being carried in proper holsters (ones where the trigger area is completely covered) because of the additional steps required to use the firearm when it is deployed. Having a pistol come out of the holster ready-to-fire is always going to be advantageous to having to remember to manipulate the safety lever, ensure the firearm is loaded, ensure the firearm is in-battery, etc. when the time comes.

Just like not wearing seatbelts is safer, since you get thrown clear of the wreck?
Officers get in waaaay more physical altercations than quick-draw duels at the OK Corral. Lack of safety switches is only more advantageous to the subjects they inevitably end up grappling with, who have one less step to deal with in removing the officer's service weapon and using it against them.
Your finger is the safety. Glock pistols have never had a safety. They have no higher rate of negligent or accidental discharges than pistols with safeties. If you are qualified to carry, a round in the chamber is what saves your life. Racking the slide(improperly) to load a round is the number one cause of jams. Nervous people tend to "ride the slide" which is pulling it back, then easing it forward. It should snap forward to strip the round from the magazine and chamber it properly.
