Winchester’s first self-loading shotgun developed by T.C. Johnson, in order to keep pace with Remington Auto-Loading Shotgun Model 11, which was developed by John M. Browning with help from T.C. Johnson. Because of the delays involved in developing a brand new design, Model 1911 was introduced on October 7, 1911. This shotgun was a recoil operated mechanism, had a tubular magazine and take-down feature. Available in two styles:

1. Plain Model 1911: 26" or 28" barrel; 12-gauge; choked Full, Modified or Cylinder; plain birch laminated pistol-grip stock and fore-end; hard rubber buttplate.
2. Fancy Model 1911: same as above, with fancy birch laminated stock.

Because of the hurry in getting this model ready for production, the shotgun demonstrated design weakness and never proved satisfactory. Discontinued in 1925. About 83,000 sold.
