Winchester Model 1907

The Winchester Model 1907 is a blowback-operated, semi-automatic rifle produced by the Winchester Repeating Arms Company beginning in 1906 with production ending in 1958. It was fed from a 5 or 10-round capacity, detachable box magazine located immediately forward of the trigger guard. The only cartridge offered by Winchester as a factory chambering in the Model 1907 was the .351SL centerfire. The energy of this cartridge approximates the modern .357 Magnum when fired from a rifle.

Variants
In addition to the standard or "plain finish" model, a deluxe or "fancy finish" model was offered with pistol grip stock and checkering on the forearm and wrist of the stock. The plain finish rifles were offered in 1907 at a list price of $28. In 1935, Winchester offered a special "Police Rifle" variant, featuring a non-adjustable rear sight, sling swivels, larger magazine release, and a special barrel measuring 5/8" at the muzzle, and rear sight dovetail moved 2 3/8" inches rearward. A barrel sleeve with Krag bayonet mount and front sight was also an option with the "Police Rifle".
