Comments:
The Walther P99 Q air
pistol, made in Taiwan for Umarex, is a very good replica of
Walther's 9 mm firearm of the same name. The outside shell of
the P99 Q is made entirely of plastic. The finish is generally
very nice, although some seams have noticeable ridges. Most of
the external controls are molded into the shell with the only
working control being the slide release lever on the left (the
lever on the right side that looks like a slide release is
actually the safety). Pushing down on the slide release causes
the front half of the slide to move forward so that the 8-shot
clips for pellets or BBs can be loaded. This is a
non-blowback design, so the slide does not move. The trigger is
double-action-only (DAO). The trigger pull is long and fairly
smooth with little of the catch that is typical of Umarex 8-shot
clip designs. (Many Umarex pistols have a distinctive catch in
the trigger pull associated with the trigger mechanism rotating
the clip.) The pull becomes noticeably harder as you approach
the breaking point. The P99 Q can fire both lead pellets as well
as steel BBs. A standard Umarex 8-shot clip is supplied for use
with lead pellets and a plastic 8-shot clip is used for BBs.
Pellets are loaded in the metal clip from the side with the
ratchet. BBs are loaded in the plastic clip from the side
opposite the ratchet.
CO2
cylinders are loaded by pulling down on the lever at the base of
the grip (it looks like the base pad for a magazine). This
causes the backstrap to flip open exposing the CO2
chamber. Pushing down on the backstrap closes the CO2
chamber as well as the "base pad". The Walther P99 Q has good accuracy
with pellets (JSB Match Diabolo) and above average accuracy with
BBs (Daisy Avanti Match). However, its measured muzzle velocity
fell far below the advertised value of 360 fps. The Walther P99
Q is a decent plinker with very good build quality for an air
pistol in its price range.

Performance (lead pellets):
Measurements were made on
10/11/2011 at a temperature of 73 ºF and 5000' elevation. A ten shot
string was fired from a bench rest at 15' using JSB Match
Diabolo pellets (7.4 gr).
The highest velocity measured was 325 fps, the lowest was 300 fps
(average of the 10-shot string was 310 fps, s = 8). A five-shot string
fired with open sights grouped at 0.48". Click the thumbnail below to see a
larger image.

The Walther P99 Q was tested with the
following pellets: Gamo Match (1.27"), JSB Match Diabolo (0.48"), H&N Finale
Match Pistol (0.82"), Crosman Premier Super Match (0.59"), and RWS Hobby
(1.27"). All groups were measured center-to-center. The
smallest groups
were produced with the JSB Match Diabolo pellets. Click the

Performance (steel BBs):
Measurements were made on
10/11/2011 at a temperature of 73 ºF and 5000' elevation. A ten shot
string was fired from a bench rest at 15' using Daisy Avanti
Match BBs (5.5 gr).
The highest velocity measured was 335 fps, the lowest was 319 fps
(average of the 10-shot string was 327 fps, s = 5). A five-shot string
fired with open sights grouped at 0.70". Click the thumbnail below to see a
