how to cut the scallop on an lda frame?
The Para LDA is a double action slide that will work ONLY on Para LDA frames. You can, however, cut the disconnector scallop in it and use the slide on any standard series 70 or 80 1911 frame. The 6â and 5â slides use standard 1911 recoil spring plugs and barrel bushing. The 4.25 inch slides use Commander type recoil parts.
