The Beretta M9/92FS series of pistols use a double/single action trigger mechanism. For those unfamiliar with what that actually means or for those presenting information to students these are the definitions that are easiest to explain and understand:

DOUBLE ACTION-(DA)

The trigger performs the dual action of cocking and then releasing the hammer with a single and usually relatively long pull of the trigger

SINGLE ACTION-(SA)

The trigger performs the single action of releasing the hammer from the fully cocked position.

The Beretta is traditionally fired from the hammer down position for the first shot and then each subsequent shot fired is in the single action mode.

Da/SA Beretta mechanism means the first shot is fired in double action and upon firing the pistol cycles ejecting the round and in the process re-cocking th hammer so each subsequent shot is fired in the single action mode until the safety is applied and the hammer safely lowered.

M9 CARRY OPTIONS:

The DA/SA Beretta hammer drop safety remains on once it is applied unless it is actively disengaged. The pistol has a double action first shot and is completely safe to carry with the hammer safely de-cocked and the safety off. There is often a belief that if there is a safety device present it MUST be applied or the operator of the pistol is being unsafe. That is patently false with the M9. The double action trigger mechanism is an inherent safety because of the requisite amount of pressure that must be exerted over the longest travel of the trigger (DA vs. SA). Safeties are not present on revolvers for that very reason. The long relatively heavy pull is an inherent safety and if a shooter inadvertently pulls the trigger with a double action pistol resulting in a negligent or accidental discharge it is solely the fault of the shooter and not a design flaw. The striker fired double-action only pistols have no external safety’s and have shorter trigger pulls than the double action on an M9 and are deemed safe for 65+% of law enforcement in the United States. I am perfectly comfortable carrying the M9 hammer down and on fire.

You can carry the M9 with the safety on or off but regardless you must train to press through the safety in case it is inadvertently placed or left in the safe position.
