1911-patterened pistols chambered in .22 LR are all the rage right now in the industry. Umarex USA, who manufacture the .22 Colt M4 Carbine, will be selling a Colt branded 1911-style .22 pistol later this year. The pistol will come in three models. The Government-style model is the base model. The Rail model features improved sights, a picatinny rail and skeletonized trigger and hammer. A Gold Cup has been mentioned but I do not know what its features are.
