Walther CP99 Compact – Part 2
by B.B. Pelletier
Yesterday we looked at the pistol, today we’ll see the downrange results.
I loaded a fresh powerlet and shot the gun without a magazine to see how many shots I’d get before the slide stopped blowing back. After shot 80 the functioning became intermittent, sometimes working and others not. The slide wasn’t blowing back far enough to cock the hammer. Since the gun is single-action only, it would not fire. By shot 90, it no longer cocked the gun on any shot, though there was still gas left in the powerlet. This is not quite as good as the CO2 version of the PPK/S, which I attribute to the somewhat greater velocity of the CP99 Compact.
To load the stick magazine, you first compress the follower spring and lock it in that position. Some guns do not lock reliably, leading to a mess when the follower releases. I’m happy to say that the CP99 Compact magazine follower locks reliably.
An odd quirk!
While shooting, I noticed that every time I pulled the trigger on a loaded but uncocked gun, a BB would fall out of the muzzle. I can hear a mechanism moving inside the gun, so apparently this pistol uses a mechanical bolt to push the BB from the magazine as the blast of gas hits it. It’s a new one on me, but I thought you should know about it. Remember, every time you put the safety on, the hammer is uncocked and has to be recocked by pulling back on the slide when the safety is taken off.
Because Crosman literature accompanied the gun I tested, I used their Copperhead BBs exclusively.
This is a minute-of-pop-can gun, not a target shooter. That said, it did respond well to a target pistol hold, with 15-foot five-shot groups shrinking from 3″ to about one. The rear sight notch is too wide for the front post, so some of the group size may be due to imprecise aiming. The sights are not adjustable, though I found them to be generally right-on at that distance.
The average velocity on a 68-degree F day was 300 f.p.s., with a spread from 292 to 311. There was evidence of the cooling effect of CO2, as the velocity did drop toward the end of the string, despite my waiting 10-15 seconds between shots. On a very hot day, you can expect these numbers to be higher by 20-30 f.p.s.
There are two safety points I wish to raise. First, when the gun is cocked, there is a red indicator visible at the rear base of the slide. I am colorblind, so the red dot has to be in bright sunlight for me to see it (Umarex, are you listening?) but it shows clearly in the photo I took. The second issue is that the slide locks in the open position after the last BB has been fired. You are prevented from firing an additional shot, just as with the firearm. This means that when the slide is forward, you should assume the gun is both cocked and loaded.
When the gun is cocked, the red signal appears under the rear of the slide.
Slide locks open when the last shot is fired.
I found the CP99 Compact to be a wonderful fast-action BB repeater. It’s just as much fun as the PPK/S and a close copy of the firearm it imitates. Airgunners should know that there is a choice between the pellet-firing CP99 and this pistol. This one’s a true semiautomatic.
