Comments: The Daisy 790 is Daisy's version of the S&W 79G. The S&W airguns were based on a design from a former Crosman engineer and the actions closely resemble the venerable Crosman Mark I and II. Daisy bought the airgun division of S&W in 1980 and produced the S&W 78G and 79G as the Daisy 780 and 790. Daisy replaced the metal loading bolt mechanism of the S&W 79G with a plastic version. It works OK, but feels flimsier than the bolt on the S&W and sometimes doesn't close properly. This specimen of the 790 has had a stronger hammer spring installed along with new seals in early 2006. Since it generates such a high muzzle velocity, the accuracy of this gun is improved by using a heavier pellet (see below).

Performance: Measurements were made on 8/29/06 at a temperature of 88 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using RWS R-10 pellets (7.0 gr). The highest velocity measured was 512 fps, the lowest was 496 fps (average of the 10-shot string was 502 fps). A six shot string fired with open sights grouped at 0.73". A six shot string fired with open sights using H&N Finale Match (Rifle) pellets (8.1 gr) grouped at 0.36". Click the thumbnails below to see larger images.

H&N Finale Match (Rifle) (6-shot string, 0.36")

Right Profile:
Front View: Power can be adjusted over a limited range by turning the screw at the back of the tube located just below the barrel. Turning the screw clock-wise increases power, counter-clockwise decreases power.
Right Side Markings:
Left Side Markings: Pulling the cocking knob all the way forward cocks the hammer. The safety can only be engaged when the gun is cocked. Once the gun is cocked, there is no safe way to decock it.
Loading Pellets:
Loading CO2: Due to the stronger valve spring installed on this gun, the gun should be cocked before the CO2 cylinder is pierced. The cylinder is pierced by a pin in the screw-on cap. The cap is screwed on tight, then the piercing button is pushed in by tapping the cap on a hard surface.
