Why do some guns have different springs?
There are two types of spring commonly used in gun actions – coil springs and V-springs. The largest springs – the ones that fire the hammers – are called main springs. The decision to use one type rather than another depends to an extent on the design of the action and also on the wishes of the manufacturer. Coil springs generally are more reliable and cheaper to make, but tend to get ‘tired’ over a period of time, so performance drops off gradually.
