Sig Sauer P365 Mach3D Features The M3D Comp is the headline feature of this pistol. A compensator at the muzzle redirects gas upward to help hold the front end down so the sights settle back on target faster between shots. The 4.3 inch barrel adds sight radius and velocity over the shorter P365 models and the 17+1 capacity of 9mm gives plenty of rounds on tap. For shooters who want faster follow up shots from a carry sized pistol this setup delivers. The optic is included in the box so the pistol is ready to run with a RomeoX Sig-Loc Compact Circle Dot already matched to the slide. A circle dot reticle gives a fast forgiving aiming point up close and a fine center dot for precise shots. Standard X-RAY3 day and night sights serve as a backup beneath the optic and the stainless steel slide wears a black Nitron finish that holds up to daily carry. An internal safety adds a layer of security without a manual lever to manage. For shooters who want a complete optic equipped pistol without a separate purchase this package is a strong fit. The XMACRO polymer frame ships with three interchangeable backstraps so the shooter can tune the grip to their hand. At 23 oz the pistol stays light enough for all day carry and two 17 round steel magazines mean a spare is in the box from day one. Sig Sauer has built the P365 family into one of the most popular carry pistol lines in the country and the Sig Sauer P365 Mach3D in 9mm carries that record into a compensated optic equipped package for sale at GrabAGun. For everyday carriers and range shooters who want capacity control and a custom fit the P365 Mach3D is a compelling choice.
