i have been reading this kind of hogwash on all types of different gun forums for many years now...that a hammer fired pistol has "more energy" or gives harder stikes to the primer.THAT IS COMPLETELY FALSE!
the fact of the matter is that a pistol can have weaker,equal or give harder strikes depending on the design and the parts used whether it's hammer or striker fired.they simply work differently.
the hammer fired uses a hammer combined with stored energy from a heavy spring to hit the firing pin so it then flys forward to strike the primer.the part that everyone seems to forget is that,there is some energy lose when the firing pin goes flying forward.the firing pin spring on this is usually small and weak and only to bring the pin back into position.
the striker fired works a little different.it tends to use a heavier firing pin and/or in combination with a relatively strong spring that "can" produce the same strike energy.it all depends on what the manufacturer had in mind or did.
everything being equal,in other words,if the manufacturer was to give the same strike force(on the primer)and designed two TDA of the same pistols but made one hammer fired(with standard practise,main spring along backstrap) and the other striker fired....you will more than likely find that the striker fired had a lighter trigger pull.(most of them out there are SA or semi-DAO) the reason for this is that you are compressing the striker spring by pulling the trigger on a striker fired BUT on a hammer fired you are compressing the main spring which tends to be much heavier.
of course,there are sooo many designs out there that it really depends.the fnp,for example,is hammer fired but does not use a regular main spring.also manufacturers tend to vary on what they do...not to mention modifications.
there's just too many variables when making a comparison.
you can also take your two pistols(one hammer,one stiker fired)to the range and study the strikes on the empty cases for yourself.if you don't see what i'm talking about,try a different pistol.
