The MK 23 is considered a match grade pistol,[12] and is capable of making a 2-inch (51 mm) group at 25 metres (27 yd).[13] The MK 23 is designed for exceptional durability in harsh environments, being waterproof and corrosion-resistant.[12] The barrel is manufactured with polygonal rifling, which is reported to improve accuracy and durability, and is much more expensive to produce.[12][14] It also features an ambidextrous safety and magazine release on both sides of the frame. The magazine release is at the rear edge of the trigger guard, which is wide enough to allow the use of gloves. A decocking lever is on the left side, which will silently lower the cocked hammer. The MK 23 is part of a larger weapon system that includes an attachable Laser Aiming Module (LAM), a suppressor, and some other features such as a special high-pressure match cartridge (.45 +P ammunition). - excerpt from wikipedia
