Product Overview
Sig Sauer P365X Macro — model/sku: SI365XCA9BX3RXS. This listing is for the P365X Macro 9mm pistol in an optic‑ready configuration featuring the ROMEO‑X SIG‑LOC Compact optic interface, an XSeries slide, and an XMacro compact grip module. Package quantity is 100 units.
Why This Product
- The ROMEO‑X SIG‑LOC Compact cut indicates the slide is configured for SIG‑LOC style red‑dot optics (source: product-273459:f009), which matters when ordering optic‑ready pistols for customers or inventory (source: product-273459:f009).
- The XSeries slide and XMacro compact grip module identify this as a P365X Macro configuration rather than a standard P365 (source: product-273459:f010, product-273459:f011), so buyers should treat it as the XMacro/P365X variant when matching accessories or marketing product features.
- Sold in bulk (Pkg Qty: 100), a commercial purchase point for dealers or distributors managing larger stock replenishment (source: product-273459:f008, product-273459:f012).
