Blowback operation is only one manner of making a gun fire, but it is interesting in its simplicity. It is a style seen in some older guns, like Bond's Walther PPK or in the Colt Hammerless 1908. The method of blowback function impacts both firearm design and performance. With the blowback style of operation, the force of the pressure caused by detonating the gunpowder within … [Read more...]

The Walther's design predates the 82, and its Russian predecessor, the Makarov, by many years (49 and 20 years, respectively), but in addition to their passing … [Read more...]
