High Quality Content by WIKIPEDIA articles! The Walther Olympia was a handgun manufactured by Walther as an improvement on the earlier Walther Target Model. It was chambered for the .22 Long Rifle, and a few chambered for the .22 Short. It was produced to equip the German team for the Berlin Olympic Games of 1936 for the rapid fire events. The Olympia design had a fixed barrel, open-topped slide and internal hammer. The Olympia had a large contoured wooden grip, which extended well below the bottom of the butt frame causing the necessity of the magazine bottom plate to be fitted with a wooden block extension.
