Owners of the P229 Legion in 9mm consistently praise the DA/SA trigger with the SRT, calling it one of the better stock triggers on a DA/SA pistol. The Legion Gray finish and G10 grips give it a purposeful, understated look that most owners prefer over flashier options. The optic-ready cut is seen as a practical addition that avoids the need for aftermarket milling.

The X-Ray3 sights get positive marks for low-light visibility straight out of the box, though a segment of owners swaps them for a red dot almost immediately given the optic-ready platform. Ergonomics are frequently described as excellent for medium-to-large hands, though those with smaller hands sometimes find the grip a touch wide.

Value opinions are mixed. The P229 Legion commands a premium over the standard P229, and some owners feel the included accessories and trigger work justify the price difference; others think the Legion package is mostly cosmetic over a well-dressed standard gun. MA-compliant capacity is a sticking point for buyers outside restricted states who would prefer a higher-capacity option.
