To keep a P320 safe, given the current situation where people are most curious...a safety mechanism can be added. The agency arms tabbed trigger adds a physical block, but one might argue that an object inside the trigger guard might depress the tab. The sig frame mounted safety could be added, but this requires a new manual of arms, like the 1911 carry.

Turns out that an agency arms tabbed trigger in titanium is the same cost as having the sig safety installed by a reputable service. Let's call it $250.

Knowing the mechanisms, is there a preferred safety to add? One would be simpler, for sure. No shipping, no waiting.

Thanks in advance for comments.

Personal opinion only, of course, and worth every cent it costs, but I firmly believe that the tabbed trigger’s contribution to fundamental safety is vastly overrated. It is one of the things I make as clear as possible to my students of the gun.
Does it help (sometimes) when the gun is handled improperly? Yes, but only under certain very limited circumstances when the trigger is somehow depressed without engaging the tab.

There have been countless unintentional discharges with Glocks and when the tab was obviously depressed along with the trigger. Do something like this as when a rookie police officer was directed to disarm a concealed carrier and the gun will function just as designed.





That is obviously just one example, but anything that touches the trigger in the usual manner will cause a discharge.

A manual safety, however, keeps the gun from firing regardless of how the trigger is molested.

When I decided that I wanted a P365 to usually carry IWB, it had to have a manual safety. No mechanical feature can excuse improper gun handling, but a manual safety provides far more protection from a screwup than a trigger tab.

None of that, however, is intended as a recommendation either way.

I agree that the tabbed trigger adds safety only when no trigger force is applied (for example, upon a drop).

The above video shows how the P320 safety stops the trigger bar from moving, preventing the sear movement and striker movement.

It also shows the superior P365 safety with true sear motion prevention.

Looks like the M17 safety would prevent more UD, if applied and operated properly.

On a competition P320, the M17 safety would allow the owner to fit an adjustable trigger to minimize pretravel and overtravel, I believe.

Despite what some would like to believe, that’s exactly what the Glock trigger tab was designed to do: make the pistol drop safe. From the Glock site:

“The trigger safety is the first safety in the firing sequence. It’s incorporated into the trigger in the form of a lever and when it is engaged blocks the trigger from moving rearward. To fire the pistol, the trigger safety and the trigger itself must be deliberately depressed at the same time. If the trigger safety is not depressed, the trigger will not move rearwards and allow the pistol to fire.

“The trigger safety is designed to prevent the pistol from firing if it’s dropped or if the trigger is subjected to any pressure that isn’t a direct firing pull.” [Emphasis added.]

This^^^^
This is what I have on my M18

Tabbed trigger, drawstring on a jacket, holster the gun with the string hanging...shoot your leg.

Manual safety!

The P320 MAX has a new home, so no need to spend the $250 on a frame safety. I did find the tabbed trigger to increase the force on my trigger finger on another P320. Trigger slap? Not sure what it is. But, not pleasant.
