About the SIG P320 X5 Legion

SIG launched the P320 X5 Legion in 2020 as the competition-tuned Legion-series flagship on the P320 chassis. Standard features include the X-Series grip module with integrated tungsten weight (43.5 oz total), Romeo-1 Pro optic-ready cuts, flat-faced match trigger, X-Ray3 day/night sights, and 17+1 capacity (21+1 with extended magazines). Each Legion ships with the challenge coin and Legion membership access.

Why the SIG P320 X5 Legion Holds Its Value

The SIG P320 X5 Legion retains value because it is the de facto entry-level competition gun for serious USPSA Carry Optics and Limited shooters. The tungsten weight is a real performance asset that drives the price floor. The Legion membership grants discounts on accessories and training, which transfers with the gun.

What Affects SIG P320 X5 Legion Resale Value

Configuration matters: 21-round Legion magazines included add $30-50 each over standard 17-round; Romeo optic installed adds 60-70% of optic retail. Pro-grade variants (X-Five Pro Carry, X-Five Legion Compact) trade differently — verify exact model. Original Pelican case and Legion paperwork add $80-120 collectively. SIG Custom Works upgrades add 50-100% of upgrade retail.
