Description
King Arms 2.5″ 357 Custom I-Co2 Full Metal Snub-Nose Revolver (Black)
This is a King Arms .357-style snub-nose revolver with a 2.5-inch barrel, full metal construction and a black finish, listed as an I-CO2 version. Short-barrelled revolvers have a classic, purposeful look, and this one makes a compact sidearm for role-play, character loadouts and anyone who simply enjoys revolvers.
King Arms is well known for its .357 revolvers, which load individual shells into the cylinder in the same way as the real thing. That loading routine, along with the swing-out cylinder and double-action trigger, gives these revolvers a hands-on feel that semi-automatic pistols cannot match.
Build and design
The name gives full metal construction, and the snub-nose barrel keeps the revolver short and easy to carry in a pocket, a small holster or a pouch. King Arms’ 2.5-inch .357 revolvers are listed with six shells, a fixed hop-up and both single- and double-action operation; please check the product images for the grips and other details of this Custom version.
The black finish suits a wide range of kit, and the compact size makes it a characterful backup for a primary replica.
How it works
This version is listed as I-CO2, which indicates CO2 power. CO2 gives a crisp, punchy shot and copes with cooler weather better than green gas. Each BB is loaded into its own shell, and the shells are loaded into the cylinder. In double action, a long trigger pull cocks the hammer and fires; in single action, you cock the hammer first for a short, light trigger pull.
Please read the manual supplied for how the CO2 capsule is fitted in this version, and for any safety and loading instructions.
Getting started
Load BBs into the shells, fit them into the cylinder and close it fully. Fit a CO2 capsule as the manual describes, then fire a few shots at a safe backstop to get used to the trigger and sights. A snub-nose revolver is at its best at close range, so practise quick, deliberate shots and fast reloads.

Compatibility
Use 12g CO2 capsules if that is what the manual specifies, along with good quality seamless 6mm BBs. Spare shells should be King Arms .357 shells made for this revolver; please check with us before ordering spares. Holsters need to suit a 2.5-inch .357-style revolver.
Care and maintenance
Always remove the CO2 capsule, or fire off any remaining gas, before storing the revolver, and never leave a capsule fitted for long periods. A drop of silicone oil on the tip of each new capsule helps keep the seals supple.
Wipe the metal with a light film of silicone oil to protect the finish, keep the shells clean and check them for damage, and use only good quality seamless BBs. Store the revolver dry, unloaded and with no capsule fitted.
Who is it for?
It suits revolver fans, role-players and collectors who want a compact, full metal snub-nose revolver with the satisfying routine of shell loading.
Please note: CO2 and BBs are not included. Box contents are not stated in our listing, so please ask if you need to confirm whether a speed loader is supplied. Always wear suitable eye protection when using any airsoft replica, and have it chronographed at your site before play.
