It ships mounted and zeroed, so the pistol is optic-ready without additional machining or mounts. Night sights are included as a backup iron sight system. The XCompact grip module is a different shape from the standard P320 compact module. It has an integrated magwell at the base for faster reloads and a slightly different grip texture. The XSeries flat trigger has a 90-degree break geometry that some shooters prefer for consistency over the standard curved trigger. The ambidextrous slide catch lever works from either side. The M1913 accessory rail accommodates weapon lights and lasers in standard sizes. The P320's modular FCU means the grip module and caliber can be changed without paperwork if desired. ### Usage Scenarios The factory optic installation makes the XCompact RXP a practical choice for shooters who want to run a red dot without sourcing a separate optic and having a smith mount it. The 3.6-inch barrel and 15-round capacity are well-suited for concealed carry and home defense. Sport shooters running Production or Carry Optics divisions will find the platform has strong aftermarket trigger and accessory support. ## Frequently Asked Questions **Q: What caliber is the Sig Sauer P320 XCompact RXP?** A: The P320 XCompact RXP is chambered in 9mm Luger. **Q: What is the barrel length of the Sig Sauer P320 XCompact RXP?** A: It has a 3.6-inch barrel. **Q: How many rounds does the Sig Sauer P320 XCompact RXP hold?** A: It has a 15-round capacity and ships with two magazines. **Q: Who makes the P320 XCompact RXP?** A: The P320 XCompact RXP is made by Sig Sauer. **Q: Does the Sig Sauer P320 XCompact RXP come with an optic?** A: Yes.

Buyers appreciate not having to source and mount a separate optic, and the ROMEO1 PRO's performance at range distances gets specific praise. Trigger quality and recoil management also come up positively. The flat XSeries trigger gets mentioned frequently as an improvement over standard P320 triggers. The modular grip system is valued by shooters who want to reconfigure the pistol later without buying a new serialized lower. Build quality is generally rated highly. Price is the main friction point. The factory optic package adds to the cost, and some buyers aren't sure the ROMEO1 PRO specifically justifies the premium versus mounting a different optic on a standard P320 XCompact. Concealability gets occasional mentions; at 25.8 oz it's on the heavier side for an all-day carry gun. ## Pricing **1 offers available** | Vendor | Price | |--------|-------| | Guns Com | $984.99 | ## Similar Products - [Sig Sauer P320 X-Five RXP 9mm with ROMEO1 PRO Optic](https://gunsnation.com/p/sig-sauer-p320-x-five-rxp-9mm-with-romeo1-pro-optic/UCE3nOgkk) - [Sig Sauer P320 RXP 9MM Striker Pro with Romeo1 Optic, Full Size](https://gunsnation.com/p/sig-sauer-p320-rxp-9mm-striker-pro-with-romeo1-optic-full-size/UCE3nOhR2) - [Sig Sauer P320 XCompact: Modular 9MM Striker-Fired Pistol](https://gunsnation.com/p/sig-sauer-p320-xcompact-modular-9mm-striker-fired-pistol/UCE3nOfwe) - [Sig Sauer P320 X RXP 9mm Optics-Ready Striker-Fire Pistol](https://gunsnation.com/p/sig-sauer-p320-x-rxp-9mm-optics-ready-striker-fire-pistol/UCE3nOgkd) - [Sig Sauer P320 Compact RX - Modular 9mm Optics-Ready Pistol](https://gunsnation.com/p/sig-sauer-p320-compact-rx-modular-9mm-optics-ready-pistol/UCE3nOQJu) - [Sig Sauer P320 RXP Compact 9mm - Striker-Fired Red Dot Ready](https://gunsnation.com/p/sig-sauer-p320-rxp-compact-9mm-striker-fired-red-dot-ready/UCE3nOhQQ) --- *Data from [GunsNation](https://gunsnation.com)*
