Sig Sauer P365X 3659SXR3P | 9mm 3.1″ Optic-Ready

The Sig Sauer P365X (model 3659SXR3P) is a micro-compact, striker-fired 9mm pistol built with a polymer frame and a stainless steel, optics-ready slide. It ships with two 10‑round magazines and factory night sights, and its compact footprint supports concealed carry and everyday carry (EDC) roles while remaining comfortable for range training. For a compatible optic under $1000, consider a compact micro red dot such as the Holosun 507K, which fits the P365-series footprint and preserves the pistol’s low profile.
