Owners of the Sig Sauer P220 Legion in .45 ACP consistently point to the trigger as a standout. The DA/SA pull is widely considered among the best stock triggers in its class, and the Legion-grade internals are credited for a noticeably smoother reset. The X-Ray3 night sights are a common point of praise, with owners appreciating the green front dot visibility in low light.

The optic-ready cut divides opinions slightly. Buyers who plan to mount a red dot see it as a practical addition, while others prefer a cleaner slide profile and would rather not pay a premium for a feature they won't use. The Legion Gray Cerakote finish is generally well-regarded for durability.

As a full-size .45 ACP, the P220 Legion is not a concealed carry favorite due to its weight and grip length, but range and home defense users are largely satisfied. Some note the 8+1 capacity as a limitation compared to double-stack alternatives, though single-stack .45 shooters tend to accept that tradeoff.
