Top view of a SIG-Sauer Tactical Operations (TacOps) pistol in 9x19mm. The slide shown features a heavy, American-made milled stainless steel slide coated in durable Nitron finish with rear Tritium night sights and a fiber-optic front sight. Because the pistol is operated by means of a locked breech, the intricately milled top of the chamber is visible in a portion of the slide. The TacOps is primarily directed towards special forces and law enforcement purposes.
