Total: $294.99

Type: Pellet air pistol
Manufacturer: Umarex 
Model: Walther CP99
Materials: Metal and plastic (polymer) construction
Weight: 1 pound 10.5 ounces (752 grams)
Barrel: 3.3 inches, metal rifled
Propulsion: CO2 x 1
Action: Semi auto, single and double action
Ammunition Type: .177 caliber pellets
Ammunition Capacity: 8 shot rotary magazine
FPS: 360

Trigger Pull: The trigger pull on the Umarex Walther CP99 is in the mid-range for its double action trigger pull with most of the effort at the beginning and middle stages as it cocks the hammer and indexes the rotary magazine, it does have a predictable release point making it easy to put pellets on target. By racking the rear slide you can put the CP99 in single action mode which makes the trigger pull much lighter and great for very accurate shots.
Accuracy: I shot this air pistol at a target from 20 feet away in a free semi rested position and it performed well getting a nice tight one inch eight shot grouping just to the left on the target. The sights can be adjusted for windage if your aim is off to one side or the other. With my preliminary Chrony Chronograph testing using 6.9 grain RWS lead pellets I got pretty close to the factory claim of 360fps with an average of right around 346 fps.

Build Quality: The Umarex Walther CP99 is a metal and polymer air gun with a good deal of metal components on the inside giving the Walther CP Sport a decent overall weight and heft. It's worth mentioning that the Walther CP99 has a full size drop out magazine for holding the CO2 cartridge that gives the air gun some additional weight and functionality. The German made fit and finish is very good on the CP99 and the plastic quality is also very good.

Realism: The Umarex Walther CP99 is licensed by Walther and is based around the Walther P99. The frame is very similar to the P99 but the slide is not as accurate in terms of the real steel but you can definitely tell the Pellet shooting CP99 is a copy of a Walther P99. One of the biggest shortcomings is the safety, the real P99 does not have a safety but Umarex decided to put a rather large safety on the right hand slide area. I do however like the working de-cocker, slide catch for loading magazines and full size drop out magazine which give the Umarex CP99 a more realistic look and feel.


  • Slide catch and de-cocker are realistic and functional.
  • Rifled barrel.
  • Sights are adjustable for windage.
  • Slide catch and magazine release are fully functional.
  • Nice full size drop out CO2 magazine.
  • Good combination of power, accuracy and CO2 efficiency (I got about 100 shots from a CO2)!
  • Rail for accessories.
  • Walther licensing.
  • German Quality.


  • Up in the higher price range.
  • Double action can have some stickier shots.
  • Kind of funny safety, not true to the real steel Walther P99.
  • No recessed barrel

Comments: The Umarex Walther CP99 Pellet CO2 Air Pistol is a nice step up from the Walther CP Sport I reviewed earlier. The CP99 is a much more accurate looking replica of the P99 and it also has more metal parts and a single and double action trigger. These added features do come with an additional $100 price tag but in my opinion are worth it. If you're a fan of the Walther line of pistols than you should probably take a look at the Umarex Walther CP99 as it would make a great addition to your airgun collection.

Handy Casual Plinker

This is a good quality handgun useful for plinking at pop cans. At 25 feet I hit 24 times of 24 shots. Target shooting is a different issue. Light weight and short barrel work against target practice. I like the gun and would buy it again.

CP99 Review

I had this gun years ago but ended up selling at one point. I recently bought it back and I can definitely say the quality is still there. German made of course. The double action trigger does required a good amount of force but single action is best for achieving those precise shots. One thing I notice from the old version I used to have is the white engravings are really popping out compared with old version which was more subtle. Nevertheless it is a fun gun to shoot and even now I still feel the same enjoyment I did many years ago. The case it comes is also of higher quality. I wish umarex will one day resurrect the Walther Nighthawk.

Great value and quality.

Germans build a great Walther line of CO2 pistols. This is one of them. Had a CPS sport and it was great. This is a great improvement over the CPS sport. It is a great 10-15 foot free hand fun shooting gun with great action. Light and accurate. Notice the safety is a bit sticky. Love the double action. As well, since it uses the 8 shot rotating mag use the RWS Meisterkugeln pellets for accuracy and ease of loading as it’s a quality line of pellets. I used daisy pellets once and these were not manufactured uniformly like the RWS Meisterkugeln pellets. The daisy pellets would bind or not go into the mag hole at all.

Thanks alot...

An odd subject line, but we'll come to that.I have been hesitating doing this review, I've done a couple others, but this one is unique. I bought this air pistol on a lark, I was in a store with a whole display of what looked to a Canadian who's only exposure to guns was American TV as a virtual armory, the one that drew my eye was the Walther - (as an an aside, come on guys... Walther? To boys of the 80's that's like 308GTB, and Farrah). Anyway; where was I? Oh yah.I'm standing there, looking bewildered that there was a display of handguns in a Canadian store when some well spoken university student says "would you like to see a pellet gun?".Being the man of the world that I am (at least in my own mind), I didn't skip a beat. "Oh yes, I am very interested in that Walther" At this point I let his salesmanship fill in a few decades of missing knowledge. Anyway, bottom line, the Walther CP99; my first modern air gun, I will not be crass to compare it to other firsts except to say this was the one the others needed to live up to.So my new adventure began, I took my CP99 apart and put it back together again so many times I figured even the most hateful drill sergeant would be impressed. Time goes by, the 7 week itch hits me for the first time. Well my CP99 is great and all... (you can fill in the rest).Bottomline, I have spent a lot of money after that little lark, scratching that constant 7 week itch, (hence the title), but if I had to chose right now, it would be my CP99 and the Baikal MP-654K that I would keep, because they; in different ways are what I am always looking for.If you are a better man than me and only want one, the CP99 is it, looks great, feels amazing, nice and heavy, shoots well, working mag and slide.Do it... but in 7 weeks don't blame me.

Nice Pistol

Great little pistol. My wife wanted a CO2 pellet gun after seeing my recent Beretta M92FS which was too heavy for her to hold comfortably. The CP99 was the perfect weight and is mostly metal which gave it a very nice feel. Getting used to the trigger but out of the box, the accuracy was pretty good. I think I may like this one better than my M92FS too!

One of my favorite !

Wow ! This is one of my favorite airgun that I own. It feel great in the hand and it's accurate. I love that the CO2 cartridge is in the ejectable magazine. I would recommend it for sure.
