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 gun shoots well with all of the following pellets:  H&N Match-Kugeln (13.4 gr), RWS Meisterkugeln Pro (14.0 gr), and JSB Diabolo Match Jumbo (15.1 gr). This airgun packs a wallop, putting out an average of 6.0 fpe with H&N Match pellets. The shot-to-shot variation for the first 20 shots is excellent (std. dev. = 3 fps).

Performance: Measurements were made on 8/08/06 at a temperature of 84 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using H&N Match-Kugeln (13.4 gr). The Air Tech Magnum converter was installed and set to maximum power. The highest velocity measured was 454 fps, the lowest was 445 fps (average of the 10-shot string was 449 fps). A seven shot string fired with open sights grouped at 0.46". Click the thumbnail below to see a larger image. Click here for a description of the measurement methods.

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.
