This is something which has baffled me for some time surrounding the "right" way to tune a pistol. It makes sense that the spring doing to full compression with wear it out rather quickly, therefore the slide should impact the frame at its most rearward position, but if that's the case why do people use shock buffers? If the slide still impacts the frame the buffer does nothing right? If the buffer shortens the stroke by inducing coil bind you still have the same problem with springs don't you?
I use a buffer, but I verify that I am not getting coil bind. Sometimes I might have to clip a little from the spring, I just use the buff to lessen the metal to metal impact.
