Shield Sights SMS/RMS Mount for SIG 320

• SIG P320 optics-ready fit: This mount is made for a SIG P320 Optics Ready pistol, giving a direct way to install a Shield mini red dot without resorting to a universal adapter.
• Shield RMS/SMS footprint: The mount uses the Shield RMS/SMS mounting standard, so it is suited to Shield-pattern pistol optics and keeps compatibility within the brand’s compact red dot ecosystem.
• Low-complexity fixed mounting solution: As a dedicated handgun mount, it provides a stable interface between slide and optic, helping maintain alignment under repeated recoil and regular carry use.
• Black finish for discreet integration: The black finish blends cleanly with modern pistol slides and optics, giving the setup a uniform appearance without drawing unnecessary attention.
• UK-made Shield accessory: Built in the United Kingdom by Shield Sights, this mount follows the same product family as the company’s SMS and RMS optics, making it a natural match for Shield-based pistol sight setups.

About the Shield SMS/RMS Series

The Shield SMS/RMS series covers a broad family of mounting products built around Shield Mini Sight (SMS) and Reflex Mini Sight (RMS) optics. Within Shield Sights’ lineup, these mounts support the company’s compact red dot platform across handguns, rifles and shotguns, giving users a consistent footprint instead of forcing a different interface for every firearm. That approach matters in practice because it makes it easier to move within the Shield ecosystem while keeping the same optic standard.

The range includes pistol slide plates, firearm-specific adapters, Picatinny and Weaver solutions, and scope-tube mounts for 30 mm and 34 mm tubes. In other words, the series is not a single mount style but a complete support system for Shield-pattern optics. For pistol use in particular, the SMS/RMS mount family is aimed at shooters who want a compact red dot installation that stays close to the slide and works with the dimensions of mini reflex sights. The defining characteristic of the series is its firearm-specific design philosophy: rather than a one-size-fits-all plate, each mount is intended to match a particular host platform and the Shield footprint used by SMS and RMS sights.

About the Shield Sights SMS/RMS Mount for SIG 320

The Shield Sights SMS/RMS Mount for SIG 320 is a dedicated handgun mount for a SIG P320 Optics Ready pistol, built to accept optics that use the Shield RMS/SMS interface. Its main advantage is straightforward compatibility: instead of adapting a Shield-pattern sight through a less specific solution, this mount is designed around the P320 optics-ready platform and the dimensions of Shield mini red dots. That makes it a sensible choice for carry, range and duty-style pistol setups where a compact optic needs a secure, repeatable mounting surface.

Because it is part of Shield’s pistol-mount system, the mount supports the practical strengths of the SMS and RMS format: a small sight footprint, low added bulk and a clean slide-mounted installation. On a handgun, that matters for presentation speed, holster compatibility and maintaining a compact overall profile. The black finish keeps the mount visually unobtrusive, while the dedicated fixed design avoids the extra complexity of more universal mounting arrangements.

For shooters already using the Shield RMS/SMS standard, this mount also helps preserve system consistency across optic and firearm. It is particularly relevant for those who want to fit a Shield-pattern red dot to a P320 without changing to a different optic footprint. The result is a simple, purpose-built interface that prioritizes fit, compatibility and a tidy pistol-mounted red dot installation.

About Shield Sights

Shield International was formed in Great Britain in 1983, and Shield Sights has long focused on firearm sighting systems for military, law enforcement and civilian use. The company is especially associated with compact red dot development: its original mini red dot sight design dates to 1996, and Shield mini sights were also sold under names including Firepoint, Tasco Optima, Trijicon RedDot and JPoint. That background is important because it places Shield among the early specialists in miniature reflex sights for handguns and sporting firearms.

Shield also developed the Close Quarter Battlesight for the UK military and later introduced the civilian-focused Close Quarter Sportsight in 2011. A notable part of the company’s design approach is its patented mini-sight mechanism intended to allow co-witnessing with standard iron sights. Alongside its optics, Shield produces matching mounts and interfaces, so products like the SMS/RMS pistol mount sit within a wider in-house sighting system rather than as standalone accessories.
