REVIEW: Umarex Walther CP99 Compact Air Pistols

This compacted version of the Walther P99 is modeled after the firearm used by special forces as their back-up pistol. This popular CO2 powered BB air pistol captures realism with its BLOWBACK, and features a single action trigger function and decocker safety is operational, with red dot indicator at the nack of the slide. Slide stop behaves like real gun, stays open when magazine is empty. The 12g CO2 cylinder loads in the back of the grip and the BB magazine releases with the push of a realistic magazine release lever. The magazine holds 18 rounds. The recoil action made live by the power of CO2 kicks the slide back giving you that oh-so-realistic feel. The customizability of this air pistol is increased a lot by the picatinny rail, making it easy to add your favorite accessory. The Umarex Walther CP99 Compact, is perfect for anyone looking for a unique pistol with hard-hitting performance and reliable internals. Be sure you buy extra magazines for none-stop action.

Pretty impressed.
By Amazon Customer
A very good buy for a bb replica. Weight is realistic and performs actions like the actual p99c. Single action trigger function and decocker safety is operational, with red dot indicator at the nack of the slide. Slide stop behaves like real gun, stays open when magazine is empty. Only flaw, when safety is on, pulling the trigger will push bbs through barrel without co2 gas fire. Great practice weapon especially when learning how to operate a real striker fire semi-auto pistol.

Walther CP99
By Lghnrse
This product is well worth the money. It uses CO2 and has blow back, like the real deal. There is a red dot that signifies round in chamber. It is very visible when aiming. The item is very accurate as well. The magazine holds 18 rounds. I purchased the 2 xtra clips as well. Worth the 14.99.
Cons: it looks too real, it uses CO2 quickly, and is heavy.

Good purchase
ByRod
I did a fair bit of research to choose the right air pistol that offered durability, reliability, and functionality. I'm not disappointed. As long as you remember to take the CO2 canisters out after use and use lubrication where instructed, the seals will last a lot longer. It isn't exactly a sniper rifle so don't expect to knock the wings off of a fly but it's a fun little backyard pistol. Ensure you buy extra magazines or the fun will quickly leave the equation when you have to constantly stop and reload.

Had to have
ByJayRT
The weight and feel on this this is really awesome. A picture perfect replica of a Walther. The realism in the blowback is very impress. Shoot very power with precision. This will be my favorite bb pistol in my armory. The only reason I gave four stars is due to the loading of the co2 a wheel under the c02 has to be tighten before turning the piercing still getting the hang of other than that pure fun.
History behind the firearm that inspired the Walther CP99 Air Pistol
The Walther P99 is a semi-automatic pistol developed by the German company Carl Walther GmbH Sportwaffen of Ulm for law enforcement, security forces and the civilian shooting market as a replacement for the Walther P5 and the P88. The P99 and its variants are also made under licence by Fabryka Broni Radom. Compact versions of the P99 are called P99C. The Umarex CP99 is an Air Pistol under licence by Walther.
Design and Development
Design work on this new generation sidearm began in 1994, and the handgun was presented in 1997 with series production commencing that same year. The weapon was first introduced chambered in 9×19mm Parabellum.
The pistol is used by the German Police in North Rhine-Westphalia and Rhineland-Palatinate and has been ordered by Bremen, Hamburg and Schleswig-Holstein, the Polish Police and the Finnish Army's special forces and military police, where it carries the designation PIST 2003 (Pistooli 2003). The Walther P99Q was also chosen in 2012 to replace older pistols and revolvers of the Finnish Police, Customs and Border Guard. This gun has also been chosen to replace the Walther P5 of the Dutch Police in 2013. In 2014 the Walther P99Q was also chosen to replace the Makarov PM of the Estonian Police and Border Guard Board.
Product Evolution: The Walther P99 was modified several times throughout its production history, as were the magazines. When the P99 was introduced the magazine capacities were 16 rounds for 9×19mm Parabellum and 12 rounds for .40 S&W. Magazines had witness holes on both sides. Later the magazine capacities were reduced to 15 rounds for 9×19mm Parabellum and 10 rounds for .40 S&W while witness holes were introduced at the rear of the magazine to view the loading condition.
Walther presented a redesigned second generation P99 in 2004, incorporating a modified trigger guard that eliminated the "ski hump", which is clearly visible in the accompanying first generation images. This was done to address user comfort concerns regarding the previous style. The first generation P99 pistols had a slide release at the left side of the frame while second generation guns may have optional ambidextrous slide stop release levers. Walther also took the opportunity to redesign the slide so the user could grip it more easily, and notably, change the proprietary accessory rail to a Weaver type. Some models built in 2005 and all later models received one more design change, an elongated magazine release.
Second Generation Models: The Walther P99 is a short recoil-operated locked breech semi-automatic pistol that uses a modified Browning cam-lock system adapted from the Hi-Power pistol. The P99 has a glassfiber-reinforced polymer frame and steel slide assembly. It can be broken down into its main parts or field stripped with a take down catch without the help of tools.
It uses an internal striker as opposed to an external hammer, with a red-painted striker tip that protrudes from rear of the slide when the gun is cocked, as well as a loaded chamber indicator on the right side of the slide.
The original, first-generation P99 had a traditional Double-Action/Single-Action trigger with a decocker. When the slide is racked completely to the rear upon loading, the trigger remains in the forward position for the first shot and the Anti-Stress mode is activated, where the striker is cocked but the trigger has the length of pull of the double-action mode. The trigger travel is 14 mm (0.55 in) long in the Anti-Stress mode, but the most of the length is slack and is similar in feel to a two-stage rifle trigger. At the end of the anti-stress travel, the pressure noticeably increases to 4.5 pounds and the user experiences a crisp trigger break and an extremely short trigger reset of about .1 inches.
All subsequent shots are fired in standard single action mode, where the slack on the trigger is much shorter, but the point of release feels the same. In order to deactivate Single-Action or Anti-Stress mode, the user can manipulate the decocker button on the top of the slide, just in front of the rear sights. When decocked from Single-Action mode, the trigger will reset to the full length of its pull. The pistol is now in Double-Action mode with a pull 7.9 pounds for the full length of the .55 inch pull. After firing the first shot in Double-Action, the pistol will be fired in Single-Action for all subsequent shots.
The striker protrudes visibly and palpably from the back of the slide when the firearm is in a constant partially cocked state. It should however be noted that the striker of the second generation P99QA variant does not protrude from the back of the slide, unless fired, as the firearm is in a constant partially cocked state.
Ergonomics were a key focus in the design of the firearm, and as a result, three interchangeable grip backstraps are included (small, medium and large) to accommodate various hand shapes and sizes; this feature permits most shooters a comfortable and efficient grip on the firearm. This adaptable grip was innovative at the time the P99 was introduced.
The slide and other metal parts of the pistol are Tenifer treated (a nitriding process also used on Glock pistols). The Tenifer finish is between 0.04 mm (0.002 in) and 0.05 mm (0.002 in) in thickness, and is characterized by extreme resistance to wear and corrosion; it penetrates the metal, and treated parts have similar properties even below the surface to a certain depth.[7] The Tenifer process produces a matte gray-colored, non-glare surface with a 64 Rockwell C hardness rating and a 99% resistance to salt water corrosion (which meets or exceeds stainless steel specifications), making the P99 particularly suitable for individuals carrying the pistol concealed as the highly chloride-resistant finish allows the pistol to better endure the effects of perspiration.
The P99 features four internal safeties, iron sights adjustable for both windage and elevation, tool-less take down, and an ambidextrous magazine release incorporated into the trigger guard. The lower forward edge of the frame also known as the dust cover has a mounting-bracket or rail interface system for attaching accessories, such as a tactical light or laser sight.
The P99 feeds from staggered-column or double-stack magazines of varying capacity. Walther also offers staggered-column magazines with a +2 baseplate that add 2 rounds to the magazine capacity at the expense of extending the grip and the pistol height by approximately 18 mm (0.7 in).
The .40 S&W caliber models incorporate a slightly larger slide in order to preserve the same recoil spring assembly used in its 9mm counterpart. The P99 is available in 4 colorations; a black frame with a black slide, a black frame with a titanium-coated slide, a military olive-drab frame with a black slide, and a desert tan frame with black slide. All three of these finishes incorporate the same black grip inserts that come with every P99. The compact versions of the P99 are only available in all black.
Accessories: Fixed metal 3-dot iron sights, fixed tritium night sights, adjustable sports iron sights, adjustable optic fibre iron sights, laser pointers, tactical lights, magazine flashlight adapters, holsters, magazines, magazine loaders, grip extenders and a suppressor kit with a 117 mm (4.6 in) barrel and protective cap for the muzzle threads and a silencer that reduces the sound signature by 33 dB(A) are offered as factory accessories.
