I have no idea why he did it that way other than he was the great man and could do as he wished. As best I recall all the guns of his that had the safety disabled were done that way but I haven't studied that many. Uncle Walt Rauch is the resident expert on Swensons maybe he'll chime in.
The home-made safety was another story, but it's on a GI gun with Colt frame and Rem-Rand slide.
