1902 M Frame Model .22 Hand Ejector), was often referred to as a 'Bicycle' gun. Iver Johnson made a similar gun--the Model 1900 Double Action small frame, a 7-shot .22, which appeared in 1900 and remained in production for 41 years." Larger calibers Introduced in the late 19th century, snubnosed revolvers such as the "Banker Special", "Sheriff's Model", and "Shopkeeper Special" versions of the Colt Single Action Army revolvers were made by Colt's Manufacturing Company. The Smith & Wesson Safety Hammerless models were produced from 1887 to just before World War II. They were chambered in either .32 S&W or .38 S&W with a 5-shot cylinder. They were most often produced with 2-inch, 3-inch, or 3.5-inch barrels. These top-break revolvers were designed for fast reloading and concealed carry as the hammer was internal and would not snag on drawing the revolver from a pocket. They also had a grip safety. They were known as "The New Departure" to reflect the company's new approach to designing revolvers. Compared to other revolvers, this design sacrifices power and range for maneuverability and concealment. Similar "hammerless" designs proved popular with other manufacturers such as Iver Johnson and Harrington & Richardson. In 1952, Smith & Wesson introduced the more modern hand ejector model the Smith & Wesson Centennial Model 40.

The Colt Model 1908 Pocket Hammerless is an 8-shot, .380 ACP caliber variant introduced five years later. Despite the title "hammerless", the Model 1903 does have a hammer. It is covered and hidden from view under the rear of the slide. This allows the pistol to be carried in and withdrawn from a pocket quickly and smoothly without snagging. The first widely used and successfully semi-automatic .25 ACP pocket pistols were the FN Model 1905, Colt Model 1908 Vest Pocket and later the Baby Browning. The FN 1905 was designed and marketed along with .25 ACP cartridge in 1905. The M1905 is a very small 7-shot, striker-fired, single-action, blow-back operated semi-automatic pistol. It features a grip safety and manual thumb-operated safety that locks the slide in the closed position when engaged. The FN Model 1910, also known as the Browning model 1910, was a departure for Browning. Before, his designs were produced by both FN
