The Challenger Arms Corporation Plainsman (pneumatic) air pistol...

[JimmieDee]

With our "new" eyes regarding the Plainsman, it's pretty clear that this is a pneumatic, because it does not have the fancy POWER CONTROL adjustable cocking hammer.

It could be either. I have further researched both the pneumatic and the CO2 variant and the pneumatic is also seen with the pellet loading shelf in front of the breech. In this example, it is possible that the pistol is cocked and only the rod is visible. Otherwise I would expect to see the knob at the end.

All the best,
Jimmie

Well, it sure looks like the pneumatic hammer rod, the CO2 hammer has a difference appearance.

It should be added: if this is what you say, then it is the rarest of all the rare, a .177 caliber CO2 pistol, a model never mentioned anywhere in the literature.
