I just picked up a Rail Gun which seems to me to have a very light recoil spring and no recoil buffer. I'm concerned that the frame and/or slide will be damaged by such an arrangement. The gun was professionally detailed and Cerakoted before I got it so I cannot believe a competent gunsmith would have let such a light spring stay in the gun if it was a problem. So do Rail Guns typically have light springs? I'm tempted to put a 16# Wolff spring and buffer in it..
