My first thought when I opened the case for the 6004 FAS by Chiappa Firearms was, “Wow, this is a nice air pistol.”
And, indeed, it is. I’ve been reviewing air rifles and air pistols for a while now, and everything about the Chiappa 6004 says to me: “This is a serious air pistol, made by people who are serious about quality.
The 6004 comes in two models, the standard, which has an ambidextrous walnut grip, and the match, which has a match-style grip with adjustable palm shelf. Other than the grips, I believe the single-stroke pneumatic powerplants for both models are identical. Airguns of Arizona sent me the standard model for test.
The 6004 stretches 11 inches from end to end and weighs just two pounds. At the extreme aft end of the pistol is an ambidextrous walnut grip that I found extremely comfortable. It seems to grip my hand with a small shelf at the top of the grip and another at the bottom. There are sculpted finger indentations which seemed to fit me “just right,” and the finger indentations and the back of the grip (where the palm wraps around) is stippled for easier gripping.
Forward of the pistol grip, the lower part of the receiver forms a black metal guard around a black metal trigger that is adjustable for trigger weight and position and pull. Plastic must be some sort of dirty word at the Chiappa factory in Italy, because I couldn’t find a scrap of it anywhere on the 6004, with the exception of a tiny o-ring at the breech end of the barrel.
Underneath the receiver, you’ll find the caliber, “Made in Italy,” and a serial number, all inscribed in white lettering. On either side of the receiver, also in white lettering, you’ll find 6004 FAS by Chiappa Firearms. There is a pin, secured by e-clips, for a pivot point at the extreme forward end of the lower receiver. Above that is the upper receiver, which has an inset opening for the muzzle and, above that, a blade-type front sight that can be swapped out if needed or desired.
At the extreme aft end of the upper receiver is a micro-adjustable notch-type rear sight with knobs for adjusting windage and elevation. On the left side of the upper receiver, just forward of the rear sight is a latch for releasing the upper receiver for loading and cocking.
That’s all there is to the 6004. The fit and finish are excellent, and everything smacks of quality. The only addition that I would make to the 6004 would be the inclusion of a small dovetail on the top of the upper receiver so that a red dot or scope could be added if the shooter desires.
To ready the 6004 for shooting, press the latch on the left side of the upper receiver in. This releases the upper receiver so that the aft end can pivot up and forward so that the upper and lower are open almost flat. This exposes the breech end of the barrel for loading. Slide a .177 pellet into the aft end of the barrel. Return the upper receiver to its original position – this requires about four pounds of effort – and this pressurizes the action for shooting.
Take aim at your target, ease the first stage out of the trigger. This required 1 lb. 9.2 oz. of effort on the sample that I tested. At 3 lb. 2.5 oz. of pressure, the second stage trips, and the shot goes downrange with a mild “pop.” Depending upon the weight, the 6004 launches pellets up to 400 fps.
With the right pellet, the factory claims accuracy of 0.08 inches center-to-center. That’s plenty good enough for 10-meter competition, air pistol silhouette, and high-precision backyard plinking. Because of its low velocity and low power, the 6004 would not be suitable for pest control, except possible mice or hornets at close range.
Now here’s a surprise: because the 6004 is produced in a modern firearms factory with efficient manufacturing techniques, the price is actually much less than I had expected; the standard model is under $400. That strikes me as a bargain for a pistol that, based on the quality of its construction, promises to deliver decades of shooting fun with occasional replacement of seals.
Til next time, aim true and shoot straight.
