Webley has a long and storied history of making some of the most innovative air pistols ever seen and the Nemesis CO2 Air Pistol is certainly no exception.  This multi-shot, bolt action pistol is filled with appealing features that will catch the eye of plinkers and target shooters alike.  

With a unique tandem magazine design, that has two cylinders providing you up to 14 rounds in .177 and 12 rounds in .22, the Nemesis throws lead down range with minimal delay between shots.  Simply pull the bolt back to index the magazine to the next pellet.  And once you're out of pellets in one cylinder, pull the mag out and flip it around the shoot the second cylinder.  Quick and easy, just the way it should be!

Powered by a single 12-gram CO2 cartridge, the Webley Nemesis spits out lead pellets at up to 450 fps in .177 and 370 fps in .22.  The impressive list of features doesn't end there.  Fiber optic open sights sit atop a 3/8" dovetail that you can choose to mount an optic on.  There's also a Picatinny rail for accessories on the forend of the pistol.  And for the left handed shooters out there, not to worry, the bolt on the Nemesis easily swaps sides.  The pistol even includes a single shot tray and has storage in the grip for your magazine.  And the grip cap also has the Allen key for your CO2 piercing screw built in, so it's always on board!  

Please note: Webley Nemesis pistols ship with the single-shot tray inserted into the breech and the multi-shot, tandem magazine inside the pistol grip. The bottom cap of the grip must be removed to access the multi-shot magazine.

Things I liked: While not heavy this pistol feels substantial in your hand. The grip is absolutely wonderful, at least for my hand. The magazine is easily loaded and works flawlessly. Bolt is easy to operate. The sights are on the cheesy side, mine is uneven on the left side of the front sight but this is easily fixed. They are easy to see and mine was dead on at 30' from the factory using CPHP 14.3s. CO2 bulbs are easy to install and give about 60 shots in the 22 caliber version. The trigger is above average IMHO for a pistol in this class. I am happy that Webley did not put an automatic safety on this gun and threaded the barrel with 1/4x20 threads.

Things I would have changed: I would try to re-design the magazine so you could just slide it over a small amount to use the 2nd drum.

What others should know: I don't think this gun will win any beauty contests but it's a good solid pistol that does what it is supposed to do. I added a 1.25x 4.75 inch LDC which makes this gun super quiet. Since it's only 1.25" in diameter is does not interfere with the sights. It does however block the CO2 chamber and must be removed each time to change CO2. No big deal. In 22 caliber the chrono shows CPHP14.3s averaged 370fps and RWS Hobby 11.9 averaged 392fps. Accurate at 30' with these pellets it wasn't very accurate at 60' but black clouds were rolling in and it started to rain so I did rush the 60' shots. I think it will do better when and if the weather cooperates.

Things I liked: Its a Webley has a 14 round magazine...eventually it becomes fun to shoot

Things I would have changed: Better user manual...easier loading process...awkward storage of accessories

What others should know: When I first started to use this gun, I thought it was the most awkwardly designed pistol I had ever purchased. It has a relatively steep learning curve. However, the more I fired it the more it grew on me. It is basically a steampunk design. Rotary top mag, bolt action, front loading CO2 port...late 19th Century meets modern materials. That is kind of the fun of it. I doubt if it will ever become one of my standards, but I can see using it when I want something unique.

  • Matthew from USA asked:

    Can you recommend a lead-free ammo, holster, and silencer for this air gun?

    • Matthew from USA:

      Okay, so found my laser and dot sight; still looking for more information on which pellet would be best to use in the .22 caliber of this gun. Looking for lead-free pellets; any suggestions, please?

  • Estil from USA asked:

    Are the sights adjustable?

    • Bruce from USA:

      Looks to me as if the option to remove them would mean that the front sight is partially adjustable.. For drift only, left-right. Certainly not for elevation..

    • Septimus from USA:

      Front sight is a dovetail that may be drifted left or right for adjustment.

    • Jordan from USA:

      No but removeable

  • Dilcia from USA asked:

    Pyramid Air, are you going to be carrying extra magazines?
