Not every air pistol uses a conventional detachable magazine. In this section, the working parts are revolver shells and cartridges for CO2 air pistols, which hold the projectile and load into the cylinder one by one. That matters if you are replacing worn parts, building a spare set for quicker reloads, or matching the right loading system to your pistol.
Our Webley lines are built around the Webley Mk VI .455 air revolver pattern. If you shoot pellets rather than steel BBs, the key point is calibre. A .22 shell must match a .22 pistol, and a spare set makes sense for range sessions where you want to reload the cylinder without stopping to refill each chamber straight away.
The Webley Mk VI .455 replacement shells we carry are a straightforward choice for owners who want like-for-like spares. They suit shooters using their revolver for informal target work and anyone who prefers the feel of loading individual shells rather than using a rotary clip or stick magazine.
The Gletcher Colt Revolver Cartridges BB are for revolver-style BB pistols that use metal cartridges loaded with steel BBs. This type of setup appeals to shooters who want realistic handling and fast, tidy reloads with a full set of cartridges ready to go.
If you are comparing BB cartridges with pellet shells, the real difference is not brand first. It is projectile type and pistol compatibility. BB cartridges suit BB-firing models, while pellet shells suit the correct pellet-calibre revolver.
If you have searched for a Webley starting pistol magazine, this page is aimed at air pistol shells and cartridges rather than blank-firing starting pistol magazines. The closest match in our current range is Webley Mk VI replacement shells for the air revolver platform, plus Gletcher Colt BB cartridges for compatible CO2 revolver-style pistols.
If you are browsing more than one type of spare, see our full Magazines range.
No. This page is for air pistol shells and cartridges, not blank-firing starting pistol magazines. Our Webley products here are replacement shells for the Webley Mk VI .455 air revolver platform.
Not in this range. The products we stock here are revolver-style shells and cartridges for CO2 air pistols, rather than box magazines for semi-auto air pistols.
The main difference is the pistol and projectile they are built for. Our Webley Mk VI shells are .22 calibre replacement shells, while the Gletcher Colt cartridges are for BB use in compatible revolver-style air pistols.
A spare set speeds up reloads and replaces shells that are worn, damaged or missing. They are also useful if you keep one set loaded for the range and another as backup.
Start with the exact pistol model and the projectile it shoots. In this range, that means checking whether you need Webley Mk VI .22 replacement shells or Gletcher Colt BB cartridges, then matching the spare to that platform.
