The Crosman model 1377 (also known as the "American Classic") is a single-shot, bolt-action, pneumatic .177 caliber pellet gun, featuring a rifled steel barrel and imitation wood checkered plastic grips. The 1377 was introduced in 1977, and has been in continuous production ever since. A separately available shoulder stock (which Crosman designates model 1399) converts the rather long pistol into a carbine. The 1377 is not a competition level target airgun, but its long rifled barrel makes it fairly accurate.

Atypically for modern pneumatic air pistols (which are mostly charged with a single action of a lever-action pump), the 1377 can be pumped to various levels; Crosman recommends at least three pumps to ensure that the pellet clears the barrel, but as many as ten pumps are advised by the manual. Crosman claims a pellet velocity of up to 600 ft/s (180 m/s) from a gun pumped ten times, which is higher than that achieved by most pellet pistols of any kind. Many 1377 owners report success with only a single pump, however; the lower velocity is accompanied by lower noise, often an advantage for those shooting indoors.

The gun is noted for being highly modifiable: a cottage industry has formed to provide its enthusiasts with parts and accessories. Examples of common modifications are custom grips and forearms to replace the factory plastic parts, custom triggers for lighter and smoother trigger pull force, custom breeches, bolts and sights, and special piston assemblies to increase pellet velocity.

there is at least 2 versions:

the 1377 that is exported to Canada, which has a special valve relief that will expel excessive gas pressure if it is pumped more than TEN times. Whereas the U.S. version has many reports of owners "over pumping' theirs to achieve a much higher fps (not recommended, as this may easily blow out seals and damage the unit)

and lately, the newer 1377 models are known as the updated 1377c, 'c' indicating Competition, although this has not yet been verified by Crosman as of this writing. one sad fact. the original versions have a magnetic chambering bolt, that will keep a steel bb connected to the bolt, allowing a downslope firing position, whereas the updated versions (1377c) excluded the magnetized bolt. hence people who buy the "updated" version are keeping their original bolts.

furthmore. the 3 versions that have been easily found in retail stores are:

First variant w/manual cocking & steel breech Phase I 1977-1981

Second variant w/manual cocking & plastic breech Pellet/BB 1981-1999 (with magnetized bolt)

Third variant self cocking pellet only w/brass bolt action 1999-Present

aside from newer versions being made with stock black and imitation walnut grips and stocks, there are at least 2 different 1377c trigger variants, one with a brass trigger and another with a black trigger. both with brass bolts.
