Its a P93DC, DC stands for De Cocker. The safety model of the P93 would simply be stamped P93. I prefer the DC models of the P series. A safety seems redundant on a hammer fired DA/SA pistol. A Decock lever is all you need.
Decocking the P series pistols may seem frightening at first, when the hammer drops with authority, but there are actually 3 internal safeties at work. The hammer is blocked from hitting the firing pin, by a "blocker". You can see this working, by looking at where the hammer would hit the firing pin when firing. Operating the DC lever pivots the "block" into place. Second, the firing pin is cammed out of position, away from the hammer. Third, a trigger block safety is also in place, blocking the firing pin from moving forward, anytime the trigger isnt pulled fully to the rear. As with any mechanical device, things can, and occasionally do fail, and safe as the P series pistols are, that doesn't excuse an operator from practicing safe firearm procedures.
