Owners of the P229 Legion in 9mm cite the SAO trigger as the platform's defining characteristic. The short reset and consistent pull draw strong approval from shooters coming from competition pistols, and the Legion Gray finish gives the gun a distinct look that most owners consider premium. X-RAY3 sights get consistently good marks for visibility across lighting conditions.

Ergonomics divide the user base. The P229 frame is compact enough for some carry applications, but the grip proportions work better for medium to larger hands. The optics-ready cut is a frequently cited advantage, and owners appreciate not having to send the slide out for milling. A recurring complaint is that SAO operation requires careful attention to carry discipline.

The Legion line sits at the high end of the P229 range and owners generally accept the price as appropriate for the factory trigger work and X-RAY3 sight package. Comparisons to standard P229 variants are common, with the Legion premium viewed as reasonable by those who value the factory-tuned SAO and as steep by those who run the platform stock.
