This airgun, a replica of what is perhaps the most famous
handgun of all time, the Colt 1873 SAA, was originally called the Hahn Model 45, later the
Crosman Model 45, and eventually became the Frontier 36 in 1970.
The revolving cylinder holds 6 BBs and the spring magazine holds
12 more. The Hahn 45 has the weight and feel of the original
Colt. This is the best BB gun replica of the Colt SAA ever
produced. This particular gun has two serial numbers stamped in
the cylinder. This pistol was resealed in July 2006.
Hahn 45 is an interesting event in the history of Crosman. It
was the first ever BB gun for Crosman. It was the first replica
model for Crosman. It's the first model designed with a die cast
housing. In many ways, the model 45 was the beginning of the
modern era for Crosman." -- Dean Fletcher,
