Our Assessment: This pistol presents in solid overall condition, retaining approximately 97% of its original finish. The exterior surfaces are clean and evenly preserved with light handling evidence, and the classic P220 profile remains intact. The conversion to DAO includes the removal of the decocker, resulting in a consistent, longer trigger pull for every shot and a simplified control layout.

Mechanically, the pistol is excellent. The bore rates 9.5 out of 10 with bright steel and sharp rifling, indicating light use. The action functions correctly with smooth cycling and proper lockup. The DAO configuration provides uniform trigger operation and was commonly adopted for duty use by agencies seeking consistency and reduced manual controls.

Historically, the P220 is one of Sig Sauer's foundational service pistols and a benchmark .45 Auto platform for law enforcement and military users. DAO conversions like this example reflect period practices from the late 1990s through early 2000s, when departments favored consistent trigger pulls and simplified handling. In this condition, with strong finish retention, a high quality bore, and correct mechanical function, this P220 stands as a clean and well executed example of a duty oriented DAO conversion.
