True Precision's Axiom Sig P365 slides are 100% designed and manufactured in the USA. Machined from a solid billet of 17-4ph Certified Stainless Steel. The Axiom P365 side is cut for the Shield RMSc optics and others with similar footprint like the Sig Romeo Zero and the Holosun 507K. The Axiom P365 slide includes a anodized cover plate to use if you choose to not use an optic. Attractive side cut window and an aggressively reduced and scalloped front with angled rear serrations gives the Axiom a unique look. Available with Black DLC or a Grey PVD finish.
