Apex Optic Mount for Romeo 1 Pro to P320 RX Classic

Description

If you’ve got a Sig Sauer P320 RX (the original Classic version) or another P320 slide cut for the Romeo 1 footprint, you already know the challenge: the newer Romeo 1 Pro optics don’t share the same mounting holes. This Apex Optic Mount solves that problem directly — it adapts your Romeo 1 Pro to fit securely on slides designed for the original Romeo 1, so you don’t have to swap slides or buy a new pistol.

Machined from billet steel with a black oxide finish, this mount is built to hold zero through thousands of rounds. The raised recoil lugs lock into the optic body, taking the shear load off the screws — that means your dot stays where you set it, even under heavy use in USPSA, IDPA, or defensive pistol classes. It’s a practical upgrade for shooters who push their gear hard and need reliability without adding unnecessary height or bulk.

Key features and real-world benefits:

• Drop-in fit for P320 RX (Classic) slides: No gunsmithing required. If your slide is cut for a Romeo 1, this mount lets you run the Romeo 1 Pro without modifying the slide or buying a new one.
• Works with or without the Romeo 1 Pro steel shroud: Keep the factory shroud for extra protection during hard use, or run without it for a lower profile. The choice is yours.
• Integrated rear notch for co-witness: The mount’s rear notch aligns with a .400″ tall front sight (not included). This gives you a usable iron sight backup if your dot fails — critical for concealed carry or competition where you can’t stop the clock.
• Steel construction, black oxide finish: Resists corrosion and wear from holster drag, sweat, and range dirt. No anodized aluminum here — steel means the recoil lugs and threads stay sharp for a lifetime of service.
• Priced at $60: A direct, affordable solution compared to sending your slide out for milling or buying a whole new optic-ready pistol. This mount does one thing and does it well.
