This is a very good reproduction of the factory original Beretta Model 21A, .22LR or .25 Auto Pistol Instruction and Maintenance Manual. This operators manual features instructions for function of the pistol, safety, dismantling, specifications and loading and firing. It also has an exploded view of the gun with a parts list. It is 28 pages long and printed on 8.5 x 11 inch paper. It is NOT an original manual. If you don't have your original manual or bought a gun without one this is a replacement
