Ruger SR1911 Competition 4.5mm BB CO2 Blowback Air Pistol by UMAREX
The Ruger SR1911 Competition takes one of the most recognisable handgun designs ever created and gives it a modern competition-inspired makeover. Based on Ruger's custom SR1911 Competition firearm, this officially licensed CO₂-powered BB pistol combines classic 1911 handling with a selection of upgraded features that make it stand out from the crowd.
Finished in an eye-catching two-tone colour scheme, the SR1911 Competition immediately looks different from the sea of standard black replicas. The polished accents, competition-style controls, and custom detailing give the pistol a premium appearance that feels closer to a personalised competition gun than a traditional service pistol.
Built with a full-metal construction and weighing 870g, the pistol has the solid feel many shooters expect from a quality 1911 replica. The strong blowback action cycles the slide with every shot, adding realistic movement and helping recreate the character that has made the 1911 platform popular for over a century.
Competition-Inspired Styling: Ruger's SR1911 Competition firearm serves as the inspiration for this replica, bringing upgraded aesthetics and enhanced controls to a proven platform.
Full Metal Construction: The metal frame and slide provide realistic weight and handling characteristics while contributing to the pistol's premium feel.
Strong Blowback Action: Every shot cycles the slide, delivering satisfying recoil and realistic operation for an engaging shooting experience.
Skeletonised Competition Components: The split commander-style hammer and skeletonised straight trigger blade not only look the part but help reinforce the competition-inspired appearance of the pistol.
Fibre Optic Front Sight: The bright fibre optic front sight allows for quicker sight acquisition in a variety of lighting conditions.
Fully Adjustable Rear Sight: Fine-tune your point of impact to suit your preferred shooting distance and ammunition.
Enhanced Grip Panels: The distinctive piranha-style grip texture provides excellent purchase while adding to the pistol's custom appearance.
Traditional 1911 Safety System: Featuring both a thumb safety and beavertail grip safety, the SR1911 Competition retains the familiar operating controls that 1911 enthusiasts expect.
A particularly nice touch is the inclusion of the flared magazine well, often referred to as a jet funnel, which helps guide magazines into place during reloads. While few shooters are setting competition times with a CO₂ BB pistol, it certainly adds to the overall character and visual appeal.

Why Choose the SR1911 Competition?
The Ruger SR1911 Competition isn't trying to reinvent the 1911 platform. Instead, it takes everything shooters already like about the classic design and dresses it up with the sort of upgrades many owners eventually add themselves. The result is a stylish, full-metal blowback pistol that feels special straight out of the box.
For shooters who appreciate traditional 1911 ergonomics but want something with a little more visual flair than a standard military-style replica, the SR1911 Competition offers an excellent balance of realism, styling, and shooting enjoyment. It's the sort of pistol that looks just as good sitting on the bench as it does punching holes in tin cans downrange.
Important — read before purchase or storage.
All CO2 and green‑gas/propane powered guns and magazines are pressure systems and must not be stored pressurised for any length of time outside active shooting. Leaving gas installed will compress internal seals, accelerate permanent leaks, and shorten the life of your gun.
Temperature & Pressure Behaviour
CO2 and propane are temperature‑sensitive: they expand and contract with temperature changes. That expansion can force gas past worn seals or, in extreme heat, rupture seals or valves — creating dangerous failures. Keep guns and magazines out of direct sunlight and away from heat sources. Cold temperatures reduce pressure and can cause low power or feed problems, so always test a gas gun in the conditions you intend to use it.Always remove or fully vent gas after use. If you’re not shooting, remove the CO2 capsule or vent/empty magazines. Do not store with gas installed.
Lubrication Recommendations
To protect internals and seals we recommend using gas with added lubricants:-
CO2: use lubricated CO2 capsules — UMAREX branded CO2 is our recommendation.
-
Green Gas / Propane: use gas with added lubricant such as Vorsk, UltraAir, Nuprol, or Abbey (Green Gas).
Seal & Lubricant Guidance
-
Apply one drop of silicone oil (for polyurethane seals only — usually green or clear seals) to the tip of every 5 CO2 capsules or before long‑term storage to lubricate the piercing nozzle and protect seals.
-
For silicone seals (typically semi‑translucent white), only use PTFE‑based lubricants (e.g. Super Lube PTFE). Do not use silicone oil on silicone seals.
-
Never use gas cartridges showing rust or visible corrosion.
Leak Expectations & User Responsibility
All gas systems will slowly leak over time. Proper care reduces the rate of leakage but cannot prevent it entirely. Leaving cartridges installed dramatically speeds up seal wear. By using or storing gas guns you accept responsibility for regular maintenance, correct lubricant use, and safe storage.We Test Before Sale
We test every gas‑powered gun prior to dispatch or handover for major leaks and function. This may mean the gun arrives with gas installed — you may choose to use this free gas or vent the gun before storage. Testing does not guarantee seal life or prevent future leaks; seals remain consumable parts.If you’re unsure about seal types, lubricant compatibility, or safe storage, ask us before purchase — we’ll give honest guidance. Failure to follow these recommendations may void warranty or return eligibility where damage is caused by improper storage or lubrication.

- Functional Moderators (Silencers/Suppressors): Moderators that reduce the sound of discharge are also classified as restricted items.
Definition and Registration:
- Component Parts: While the VCRA does not explicitly define "component parts," the Home Office interprets this to include pressure-bearing parts such as barrels, cylinders, reservoirs, and pistons.
- Accessories: Only moderators (silencers) require registration by dealers.
Legal Requirements for Transfer:
- In-Person Transfer: It is an offence under the VCRA to transfer these restricted items through standard postal systems or to the end customer directly without the presence of both the buyer and either the seller or a representative of the seller.
