Apex Optic Mount for Romeo 1 Pro to P320 RX Classic

Description

Designed for shooters who demand a secure, zero-compromise optic mounting solution, this Apex mount lets you fit the popular Romeo 1 Pro onto your Sig Sauer P320 RX Classic slide. At just $60, it’s a practical upgrade that avoids the need for a new slide or expensive milling work — especially important for those of us navigating California’s roster and parts compatibility rules.

Machined from a single billet of steel and coated with a black oxide finish, this mount is built to handle repeated recoil without shifting or loosening. The raised recoil lugs are a key feature: they lock the Romeo 1 Pro into position, preventing the optic from sliding under hard use. That means you spend less time re-zeroing and more time shooting — whether at the range, in training, or for home defense.

Real-world fitment: This mount is specifically engineered for the P320 RX Classic slide, which is factory-cut for the original Romeo 1 optic. If your pistol has that cut pattern, the Apex mount adapts it to accept the Romeo 1 Pro without any permanent modifications. It also works with other P320 slides that share the same Romeo 1 footprint, making it a versatile option for CA-compliant P320 builds.

Key specs and benefits:

• Direct mount to Romeo 1-cut slides — no adapter plates or extra hardware required for most P320 RX Classic pistols.
• Works with or without the factory steel shroud on the Romeo 1 Pro. Use the shroud for added protection in duty or holster carry, or run it bare for a lower profile.
• Integrated rear notch co-witness — the Romeo 1 Pro’s built-in rear sight aligns with a .400-inch tall front sight (sold separately). This gives you a usable iron sight backup if your optic goes down, which is a practical advantage for defensive use.
• Steel construction, black oxide finish — resists corrosion and wear, even in humid California coastal conditions or during frequent range sessions.
• No gunsmithing required — installs with basic tools in minutes, so you can keep your pistol in service without a trip to the shop.

Because this mount is a drop-in part, it does not alter the firearm’s serialized frame or require any roster-exempt modifications. It’s a smart, legal way to upgrade your P320’s optics capability while staying compliant with state laws on handgun parts.
