The P211 combines a 2011-style handgun with a single and double action trigger along with compatibility with Sig Sauer's proven P320 series magazines. A new MACH3D compensator reduces muzzle rise by 30% allowing for faster follow up shots. The P211-GTO also comes optics ready with Sig Sauer's new SIG-LOC PRO mounting interface designed to improve optic stability through 5 total contact points between the slide and the optic. This model features an all-black finish and includes one 23-round magazine and two 21-round magazines. *Optic is for display purposes only and is not included.*
