The 19 >6 Olympic games in Berlin witnessed the beginning of an amazing record of consistent accuracy. In that year, the first five winners in the rapid-fire matches won their laurels with the then-new Walther Olympia .22 calibcr automatic pistol. Since that time, the Olympia design has become the overwhelming choice of International shooters.

Of course the war put the W alther plants in Germany out of the gun business, and Fritz Walther moved to Switzerland after the war. He sold the manufacturing rights for the Olympia to the Hammcrli Arms Co. of Lenzburg, Switzerland, and was consulting engineer for the firm. Walther picked the right firm to carry on the Olympia production, for the Hammcrli guns have been renowned for their accuracy and workmanship for a long, long time. The gun is so similar that many parts of the Hammcrli Olympia are interchangeable with the original Walther Olympia.

E. J. Hoffschmidt has an extensive background as a gunsmith, engineering draftsman, and researcher, with a particular interest in automatic pistols.

Remove the magazine and check chamber to be sure the gun is empty. Remove the weights. Pull down on the front of the trigger guard (MM), push it to the side until it catches on a lip in the receiver (S). Draw the slide to the rear, lift it up off the receiver, and ease it forward over the barrel

To remove the safety, lower the hammer (Y) to fired position. Depress the magazine catch (NN), lift the catch (LI) a bit as shown, to prevent it scratching the finish, and rotate it up over the edge of the receiver to the position illustrated. The catch will then spring free of the receiver

There arc two models currently being manufactured; one. the Special Olympia with a 9I/2-inch barrel and a trigger pull of \Vi pounds, and the Standard Olympia, with a IVi-inch barrel and a trigger pull of at least >3 ounccs.

The pistol is one of the few that has been expressly designed for target shooting. The gun is not for plinking. The adjustable grip, the trigger pull, and the sear mechanism were all designed for one purpose—to allow the shooter to make the highest possible score over a challenging course of fire.

On the earlier model Hammcrli Olympia. the front sight is adjustable for elevation, and the rear sight for windage, but the new model now available incorporates an Americanized rear sight. That is. the rear sight is adjustable for elevation and windage. The addition of a hold open latch and buffer spring also improve the pistol a great deal. The lack of a hold-open latch in the earlier model makes it awkward to comply with the open-bolt rule enforced at most ranges. Like its predecessor, the Hammcrli Olympia is made in .22 long rifle and .22 short» While the .22 calibcr ammunition docs

Old Carbines Single Shot Short

The extractor (B) is retained by a spring-loaded plunger (C). Using a small screwdriver, push the plunger back into the slide (A). If the slide is turned on its side, the extractor will then drop out. Ease up on the plunger (C) and it will come out with its spring (D)

Walther Olympia

A spare firing pin (L) and firing pin spring (K) are supplied with each new gun. To remove the old parts, hold the slide (A) upside down in a vise, and tap the firing pin retaining pin (F) out, as shown. The firing pin and spring can then be lifted out of the slide not have the kick of the larger center-fire ammunition, it is powerful enough to get the gun off the target. The muzzle brake and weights are added to combat this thrust. A muzzle brake of this type tends to keep the barrel down. While the weights have the same cffcct, they perform another function, too. The weights have a steadying influence, allowing the gun to be swung more easily from target to target during Olympic rapid-fire.

Since the pistol is a blowback-operatcd weapon, there is no locking mechanism to make the take-down procedure involved. The only point in the take-down that might be called unorthodox is the method used to remove the recoil spring and spring guide. The front end of the receiver has to be sprung away from the barrel a bit to free the end of the spring guide from its stop in the receiver. This is accomplished by driving a brass wedge or screwdriver between the barrel and the front of the receiver. While this mav seem to be deforming the receiver, it is nevertheless the method used at the factory. The receiver is spread so little that it docs not harm the gun. ^ # #

Lgv Walther Trigger Tension Screw
