If you’re after a reliable, hard-recoiling full metal sidearm ideal for a British Army loadout, the WE EU17 Gen.4 Gas Blowback Pistol, Pre Two-Tone is a fine choice. A full metal build with a hefty alloy slide, alloy outer barrel and high-density polymer frame, the EU17 Gen.4 replicates the most popular Military/Law Enforcement sidearm on the planet in its “Gen.4” form, a close match for the sidearms issued to the British Army, known as the L131A1.

This version comes in VCRA-compliant Two-Tone Blue, so no UKARA is required, and there’s no need to wait for a two-tone service.

Externally, it’s built with practicality in mind. You get a 20mm Picatinny rail up front for a torch or laser, along with an 11mm CW female threaded outer barrel, ready for a tracer or suppressor with an 11mm CW Female Thread Adapter.

Ideal for many modern military loadouts, from the British Army to the New Zealand Armed Forces, and almost every Armed Police unit in the UK, the EU17 Gen.4 is ideal for realism-focused skirmishers who appreciate the combat-ready simplicity loved by soldiers and law enforcement worldwide. Whether you’re a budding milsimmer or you’re after a detailed replica inspired by what is arguably the best combat sidearm around, the WE EU17 Gen.4 Gas Blowback Pistol, Pre Two-Tone will put a big smile on your face!

Quick Start Guide [VIDEO - How to Load a Green Gas Magazine]

  • Load your magazine: Pull the follower down to the bottom of the mag and hold it there. Load BBs through the wider opening at the front using a speed loader or by hand.
  • Fill with gas: Turn the magazine upside down so the fill valve is facing up. Press the nozzle of your Green Gas can into the valve and hold for 5–10 seconds.
  • Wear eye protection: Always put on proper eye protection before handling your airsoft gun. Make sure anyone nearby is also protected.
  • Insert the magazine: Keep the barrel pointed in a safe direction and your finger off the trigger. Push the magazine into the mag well until it clicks into place.
  • Ready to shoot: Only use your airsoft gun in safe environments. Never shoot at animals or anyone not taking part in an airsoft game.

FAQ

Q: What Ammo/BBs do I need?

A: You'll need 6mm plastic Airsoft BBs between 0.20g and 0.28g in weight. We recommend 0.25g BBs for the WE EU Series for both indoor and outdoor gameplay. Never attempt to shoot any form of metal ammo or "paint" ammo, as these are not designed for Airsoft guns and will cause internal damage.

Q: What Gas do I need?

A: Standard pressure Airsoft Green Gas (NUPROL 2.0/2.Zero, VORSK V6, ASG Ultrair, Abbey Predator, SMART Green Gas) is ideal for this pistol in most weather conditions. If the temperature is below 10°C and your pistol cycles sluggishly, we recommend using Red Gas (NUPROL 3.0, VORSK V8, etc).

Q: How do I maintain my GBB pistol?

A: We recommend cleaning the slide engagement rails and applying silicone lubricant after every extended firing session (100 BBs+). See our Video: How to Lubricate an EU series GBB Pistol for more information. Regular maintenance ensures you get the best feel and performance from your GBB pistol, keeping the slide cycling efficiently with minimal friction and preventing jams. Never use WD40 or Petroleum-based lubricants on an Airsoft gun, as these will damage the rubber seals.

Q: How old do I need to be to buy and use an Airsoft gun?

A: Airsoft guns can be legally purchased by anyone over 18, but can be used by anyone of any age. We recommend adult supervision for users under 14 years old, at the parents' discretion. Most skirmish sites have a minimum age of 14 or over for attendees, some of which require under-18s to attend with an adult.

Q: Can I buy this for someone else?

A: Yes, provided you are over 18 and either have a Specific Defence under the VCRA, or choose a "Two-tone" colour variant. This variant is already finished in Pre Two-Tone Blue, so you can order without UKARA and use our fastest shipping service!

Q: Do I need a UKARA or a License?

A: Not for this variant, as it is already finished in Pre Two-Tone Blue, ready for immediate dispatch. You’ll need a UKARA membership or other valid defence under the VCRA to buy this item in realistic colours (Black, Tan, etc.). There’s no license required to own or buy Airsoft guns.

Q: Does it hurt to get shot with this?

A: It can sting, similar to a rubber band snap on bare skin, but less than a paintball. The sensation depends on distance, clothing, and protective gear. Airsoft guns produce muzzle energy around 1/14th of the average Paintball Marker, so hits hurt far less than hits from paintballs.

Q: Is an Airsoft gun dangerous?

A: Only if misused. Airsoft guns must never be brandished in public or in an area visible from public land. When transporting an Airsoft gun, ensure it is unloaded and concealed in a gun bag or case. When shooting, both the shooter and any spectators must use eye protection. It is also important that you don't shoot at targets beyond your property boundary.
