I have seen that in order to remove the slide, you had to rack the slide, flip up the safety lever, push the pin out, flip safety lever down, move slide to front and raise the rear of the slide to remove it. Seems like a lot of steps. Could you not drill or notch the slide to have direct access to the pin? Also, I have heard that the holes for the rear pin can be tapped to 6/32 and a 6/32 x 3/4" set screw can be installed. Should these mods be done?
