The SIG SAUER P220 DA/SA pistol has long been recognized as one of the most accurate out-of-the-box .45s available with a reputation for durability. Now SIGARMS offers the latest version of this service pistol - the P220 Single-Action Only. This 8 plus 1 capacity pistol features a crisp 5-pound SAO trigger that breaks like glass and an ambidextrous thumb safety. The combination of SAO trigger, cold hammer forged barrel and near perfect lock-up offers shooters accuracy that sets the P220 apart from other 45s. The P220 SAO slide is machined from stainless steel bar stock and finished in a durable Nitron finish. The lightweight alloy frame is hard-coat anodized and outfitted with a Picatinny rail for tactical versatility. The P220 SAO comes with either contrast or SIGLITE night sights and is also available in Two-Tone with a Natural Stainless slide. Optional 10 round magazines are available separately from SIGARMS.
