The Trinity PiRho features a fully integrated high performance compensator. This unique design leverages the most advanced fluid dynamics in the industry. As a result their compensator technology is not pressure dependent but instead takes advantage of the supersonic transition of the gasses to deliver unparalleled recoil reduction while adding no extra length. This, combined with a lightened slide dramatically reduces the recoil and muzzle rise of the Sig P320. The normally sharp recoil is reduced to a gentle, straight back push. Incorporated sight tracking tremendously shortens time of followup shots on target. For the casual shooter this increases the enjoyment of plinking and puts you a leg up over your fellow shooters. The competition shooter will see reduced target acquisition time and increased accuracy and repeatability. Stainless steel materials and PVD coating ensures long life and durability. A selection of PVD coatings allows you to meet your aesthetic preference. The standard Dawson sights aid in positive target acquisition. Slides are pre-machined to accept RMR compatible red dot sights, giving even greater flexibility for sighting preference. Because the compensation is fully integrated into the slide assembly the handgun fits perfectly into a standard holster designed for the Sig P320. The Trinity PiRho does not require a threaded barrel so it is legal in all 50 states.
