Or double action only semi-automatic pistols.
“Or double action only semi-automatic pistols.”
No, a double action only pistol has the same trigger pull every time, there isn’t an external hammer or a way to cock it.
A DS/SA pistol has a difference between the DA and SA pulls but it cocks itself and the only shot with a heavier trigger pull is the first.
The only pistol that has a hard pull that can be made softer by coking it is a double action revolver.
