The trigger on a single action semi-auto firearm only releases the hammer, making the trigger very light. This particular 3D model is of a 1911-style semi-auto. It's called a 1911 because this style of pistol was put into service by the US military in 1911. Single-action semi-autos are not ideal for a new shooter, as they're somewhat complicated, but they are often loved by experienced shooters.
