In the past, there have been questions regarding the Wilkinson Arms Sherry .22LR semi-auto pistol. What I have learned is that there are three variations. The first variation has a Wilkinson marked frame and a Sherry marked slide. Wilkinson named his firearms after his daughters. The second variation has a Wilkinson marked frame and no Sherry, or any other marking, on the slide. Both of these variations have an internal hammer and are marked Parma, Idaho. The third variation, the Auto Nine, was made by the Auto Nine Corporation of Covena, California, and marked accordingly. The Auto Nine is striker fired, resulting in a slide obviously different than the Sherry. The change from internal hammer to striker fired may have been cost saving or it may have been to facilitate dis-assembly, which was far more complicated with the internal hammer Sherry. Both the Sherry and Auto Nine, for a diminutive pistol, have an unusually high magazine capacity of nine cartridges, eight in the magazine plus one in the chamber. Most full size .22LR semi-auto pistols exceed this capacity by only two or three cartridges. The brochure is for the Wilkinson Arms Sherry manufactured in Parma, Idaho.
