The Night Fision NF SIG-180-240-238-YGZG NF NS S365 is an Optics Ready Stealth night sight set engineered specifically for the Sig Sauer P365 and compatible P320 slides. Built from rugged CNC-machined steel with a matte black nitride finish, it uses extra-bright tritium inserts and a high-visibility yellow front ring to deliver a crisp, fast sight picture in both daylight and low light. The U-notch rear and carefully tuned blade heights are designed to provide an approximate lower one-third co-witness with popular micro optics such as the Holosun EPS and EPS Carry when direct mounted.

This sight set is ideal for everyday carry, home protection, and regular range practice where reliable visibility matters around the clock. The contrasting yellow front and subdued rear dots help your eye lock onto the front sight quickly, supporting confident alignment whether you are shooting in bright sun or dim indoor lighting. Thoughtful machining and corrosion-resistant finishing make it a durable upgrade for shooters who rely on their Sig pistols, reflecting Night Fision’s focus on practical innovation and dependable performance.
