This 8+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 outstanding 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 an accessory rail for tactical versatility. The P220 SAO comes with either contrast or SIGLITE night sights.
