Comments: This air pistol was manufactured by Smith & Wesson based on designs from a former Crosman engineer, which explains the close resemblance of the action of the 78G and 79G to the Crosman Mark I & II. The 78G is .22 cal and the 79 G is .177 cal. Early models of these guns had adjustable triggers, but this specimen is a later model with a non-adjustable trigger. From 1971 to 1973, these guns were made in Tampa, Florida. In 1973, S&W moved production from Florida to Springfield, Massachusetts. In 1978, production was moved back to Tampa and remained there until S&W sold their airgun division to Daisy in 1980. Daisy manufactured versions of the S&W guns as the Daisy 780 (22 cal), Daisy 790 (177 cal), and Daisy 41 (177 cal).  This specimen of the S&W 79G is a very hard hitter, averaging over 500 fps with RWS R-10 pellets. Other good pellet choices are JSB Match Diabolo (8.0 gr, avg. vel. = 451 fps, grouping = 0.37"), H&N Finale Match Rifle (8.1 gr, avg. vel. = 465 fps, grouping = 0.51"), and H&N Finale Match Pistol (7.3 gr).

Performance: Measurements were made on 8/03/06 at a temperature of 84 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 516 fps, the lowest was 466 fps (average of the 10-shot string was 506 fps). A six shot string fired with open sights grouped at 0.51".

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 puts the gun in the hi-power setting. Pulling the cocking knob half-way forward puts the gun in the low-power setting. 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: 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.
