I started by measuring the compressed lenght of a factory recoil spring. This include the rod base to a total of .950 or little less than an inch. During recoil rearward travel, before 1.260 inches the slide will be stopped by the frame not fully compressing the spring. While trying slowly I clipped coil after coil of spring. I ended up removing eight coils and still can dry cycle a round. My fear is that a lighter spring will sure bang up the frame. I have a plan of using a recoil buffer before I shoot this tweaked recoil spring. Any help of what buffer to use?
