Comments: Comments: Daisy bought the tooling for the Hyde BB Pistol (originally manufactured by Floyd Hyde Engineering) and reintroduced the Hyde as the Daisy CO2 100. The Hyde air pistol itself was actually a conversion of the .22 cal Wamo Powermaster pistol introduced in 1956. The CO2 100 was the first semi-auto replica repeater made by Daisy and also its first CO2-powered airgun. The Model 100 was only produced in 1962. The trigger on this gun feels like a true single action semi-auto although it operates the elevator in addition to releasing the sear. Daisy reworked the gun and reintroduced it as the Daisy CO2 200 in 1963. The Daisy 100 holds 200 BBs in a hopper from which 5 BBs at a time are fed into a spring-loaded internal magazine. The Model 100 is pretty fragile and not many of them still work (leakers). This specimen holds air and shoots very well.

Performance: Measurements were made on 9/29/06 at a temperature of 77 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using Crosman Copperhead BBs (5.1 gr). The highest velocity measured was 454 fps, the lowest was 422 fps (average of the 10-shot string was 435 fps). A six shot string fired with open sights grouped at 0.76".

Loading BBs: Up to 200 BBs can be poured into the port at the rear of the gun. To load BBs into the spring-loaded magazine (max = 5), point the gun down and shake it. Then, raise the gun up to 45 with the left side facing down. Push the follower forward and BBs should drop into the magazine. As the hopper gets low on BBs, it is harder to get BBs to drop into the magazine. BBs can be unloaded by shaking them out of the port in the back.

The rear sight is adjustable by sliding the sight blade up/down and left/right. The range of adjustment is small.

Loading CO2: There is no piercing pin O-ring seal on this model. To load a CO2 cartridge, hold it in place -- centered under the pin -- while tightening the piercing screw. When the cartridge is pierced, turn the screw one more revolution to seal the cartridge. The Model 100 and 200 have a tendency to go fully automatic when the gas pressure gets low or if the gun is fired rapidly causing the valve to frost over.
