BuckMark 22 pistol weight variations

[edwardh1]

What causes many of the models to be 25 oz in weight (example Buckmark Challenge) while most of the others (Buckmark Camper) are 34-35 ounces and they look the same and all have alloy receivers?

I may be mistaken, but it could be due mainly to barrel length and circumference.

Some use thinner barrels and have a light weight sleeve over the barrel, while others have a full heavier barrel.
