Comments: 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.

"The 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, American Vintage Airguns, 2006.

Performance: Measurements were made on 7/20/06 at a temperature of 85 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 364 fps, the lowest was 320 fps (average of the 10-shot string was 350 fps). A five shot string fired with open sights grouped at 1.54".

Right Profile:
Front View:
Right Side Markings: The "Pat. Pending" marking identifies this specimen as having the second style of frame marking for the Hahn 45.
Left Side Markings: The original markings on the Hahn 45, like the one below, had the left side markings in larger print with the "45" made out of dots. Later versions used a smaller style print (see left).

Loading BBs: Pull the spring follower back all the way and load BBs until the tube is full. Rotate the cylinder to allow a BB to fall into each of the six chambers. Add six more BBs to the BB tube.
Loading CO2: Insert the CO2 cylinder into the valve seat and tighten (finger tight only -- no tools) the cylinder nut. Cock the gun and fire it two or three times to pierce the cylinder. Cocking the gun pierces the cylinder, not over tightening the cylinder nut.
Holster: This is the Hahn 45 fast-draw leather holster produced by Crosman during the peak of the fast-draw craze. The holster set is complete with the cartridge case (for CO2 cartridges) and the original hang tag.
