Smith & Wesson Lemon Squeezer

The Smith & Wesson Lemon Squeezer or the "Safety Hammerless" is a double action revolver that was produced in the late 1880s by Smith & Wesson. The revolver was chambered in .32 S&W and .38 S&W calibers; these calibers were discontinued just before World War 2. The gun went through a few changes until 1952, when the safety hammerless concept was applied to Smith & Wesson's J-frame. The finished product became the Model 40 and 42 chambered in .38 Special. The gun is known as the Centennial as it was produced in the 100th anniversary of the founding of Smith & Wesson.

32 and 38 Safety Hammerless models
The Smith & Wesson 38 Safety Hammerless models were produced from 1887 (1888 for the 32) to just before World War 2. They were chambered in either .32 S&W or .38 S&W with a five-shot cylinder. They were produced with a 2-inch, 3-inch, and 3.5-inch barrels. They were top-break revolvers designed for fast reloading and were named "The New Departure". Minor design changes were made to these revolvers over the years, resulting in several different design models, as termed by collectors. The first model was manufactured between 1887-1902. The 38 was based on S&W's medium "Number 2" frame, while the 32 was based on the small "1½" frame.

Model 40
The Model 40 originally came out in 1952 as the Centennial and was changed to the Model 40 in 1957. The Model 40 is chambered in .38 special and has a five-round capacity. It is a snub-nose revolver with a 1 7/8-inch barrel. It is built on Smith & Wesson's J-frame and weighs 21 oz. empty. The revolver was made with a grip safety as some shooters could not get used to the idea of firing a revolver without cocking the hammer. Smith and Wesson reintroduced this model in 2007 as a collector's piece with some models featuring a case hardened finish by Doug Turnbull.

Model 42
The Model 42 came out in 1952 as the Airweight Centennial but was changed in 1957 to the Model 42. The gun was the same design as the Model 40 except that its frame was made of an aluminum alloy, resulting in a lower weight than the Model 40. The Model 42 was discontinued in 1974.
