Short answer, yeah if you send it to S&W for modification. I sent my 4516-1 back to S&W in the mid 90s and it now takes the dual spring set. I'm not sure if they did a little machining, but they added a washer type plug in the front of the slide where the recoil spring guide pokes through. The diameter of the dual spring guide is much smaller than the one for a single spring.
S&W use to do this modification routinely on 4516-1 pistols returned to them with feeding or ejection issues. Call customer service and tell them you want a call tag for you 4516-1 to send back for the dual spring set modification because you've started to have feeding/ejection issues. Good luck.
