Description
If you're after a full metal Hi-Capa with professional presentation and a surprisingly high-quality build, the Golden Eagle 3340 Hi-Capa 5.1 Twist GBB Pistol should be on your shopping list! Supplied in a hard pistol case with a stylish ported slide, light-enhancing iron sights, a combat-optimised flared magwell, and trigger guard undercuts, the 5.1 Twist is at the peak of Hi-Capa handling, with impressive features on board which make it look far more pricy than it actually is.
Inside, we're even treated to a robust steel hammer, steel trigger and a 6.02mm tightbore inner barrel for an accuracy edge with high-quality BBs. If you're looking for a solid beginner sidearm with a premium look but no premium price, the Golden Eagle 3340 Hi-Capa 5.1 Twist GBB Pistol is a safe bet!
Starting at the front, we can find 11mm CW female threading at the tip of the 5.1-inch aluminium outer barrel, allowing a tracer unit or suppressor to be fitted using an 11mm CW female to 14mm CCW male thread adapter. If you're planning on rocking a tracer with the 5.1 Twist, we recommend the Eshooter Flare-M, as it is supplied with the correct adapter in the box.
The outer barrel itself is finished in matte gold, providing a glimpse of its glamorous colour finish through the ports on the sides and top of the slide. To make matters even more special, the barrel features unique spiral fluting running its entire length, visible through the slide ports and at the chamber. The gold barrel adds an instantly recognisable "custom" look, and the spiral fluting only adds to the aesthetic!
The slide itself is ported at the front, with dynamic, angled ports on each side and a long oblong port on top. The side ports can also be used as makeshift slide serrations, allowing for easy racking from the front or rear. The ported slide design helps cut down weight to improve slide cyclic speed, along with adding considerably to the stylish Hi-Capa aesthetic.
The sights of the Hi-Capa 5.1 Twist can be found on the top of the slide. The front sight is a fixed light-enhancing sight with a red insert, allowing for fast target acquisition, even in low-light situations. The rear sight is a serrated "anti-glare" open sight which combines well with the light-enhancing front sight to prevent accidentally mixing up the sight dots and pulling your shot off. Both sights are made from steel, a big plus for strength in this affordable package.
The rear sight is fully adjustable, allowing for elevation adjustments(up and down) by turning the screw on the top using a flathead screwdriver. The windage can be adjusted using the screw on the right side of the sight, which will allow you to move the sight picture left to right. Adjustable sights very much suit the competition-esque styling of the Hi-Capa 5.1 Twist, allowing extra precision so you can land shots on small targets with ease.
At the rear of the slide, we can find stylish angled serrations to provide positive control over the slide of the pistol, meaning no matter the weather conditions, you will still be able to cock the slide, with or without gloves. The styling of the serrations matches perfectly with the shape of the front slide ports, providing the professional aesthetic of a completed piece.
Moving down to the frame, we can find the standard Hi-Capa layout of an alloy frame with a modular, polymer pistol grip. The frame features a 20mm Picatinny rail at the front, which allows for a tactical flashlight or aiming laser to be added for low-light environments or CQB.
The slide release catch can be found on the left side of the pistol, just above the trigger, and is a slightly enlarged design to enable those with smaller hands to use the control effectively whilst remaining tight to the frame to prevent snags. The magazine release can be found on the left side of the grip and is an extended design to allow for easy and fast access when time is of the essence.
The grip itself is constructed from high-density polymer and features dot texturing on all sides to provide the gripping qualities necessary for use in all weather conditions, with or without gloves. As a part of the Hi-Capa design, the trigger guard is integrated into the pistol grip module and includes undercuts for both the strong hand and support hand, encouraging a high grip on the pistol for better recoil control.
At the base of the grip, we can find a magazine well extension with a bevelled inner wall, also known as a magazine well flare. This part is intended to help speed up reloads by providing a widened route to the magazine well, allowing for "eyes up" reloads and easier reloads on the move. The magwell flare included on the 5.1 Twist is a combat-optimised style, complete with cutouts on either side, which allow for retention reloads or the extraction of stuck or fouled magazines.
The manual safety catch can be found at the rear of the pistol, and is mirrored on either side to allow for left or right-handed use. This manual safety can be activated whether the pistol is cocked or not and will lock both the trigger and slide when pushed upwards. When not in use, the safety does double duty as a "gas pedal" style thumb rest to encourage a consistent grip and assist with controlling muzzle rise during rapid fire.
At the rear of the frame, we can find our secondary safety device: the "beavertail" grip safety. This safety prevents the pistol from being fired unless it is pressed in, ensuring the pistol will not fire when dropped and allowing you to safely carry the Hi-Capa, "cocked and locked", with its legendary light trigger. The beavertail present on the Hi-Capa 5.1 Twist is an extended design, featuring texture on the rear surface for additional grip and an extension to ensure the safety is disabled as soon as the pistol is gripped.
Just above the grip safety, we can see the hammer, which is a low-profile skeletonised design intended to reduce the chances of "hammer bite" and prevent the hammer from snagging on your gear as you draw. The angular design of the hammer sits right in line with the visual language expressed by the rest of the pistol, and also includes linear texture on the upper surface to allow for greater control if you need to de-cock the Hi-Capa.
If you love pistol builds focused on handling qualities without garish looks, the Golden Eagle 3340 Hi-Capa 5.1 Twist GBB Pistol is a superb choice. Borrowing the Gold Match aesthetic with Golden Eagle's unique Twists (wink), this full metal alternative to the legendary TM is an impressive piece for the price!

Joule Charts
Special Instructions
These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
