I am looking to stock up on some replacement parts for my 4516-1 while they are still available. Does anyone know if the sideplate assembly for the 4506 is compatible with the 4516-1? I see a sideplate assembly for the 4506 available on Numrich, but am unable to find one mentioned as compatible with the 4516-1 in stock anywhere. If the parts are not the same, does anyone know of where I may be able to find a replacement sideplate assembly for my 4516-1?

My parts book lists the sideplate (4506/4516) as the same part number.....10860.

According to the S&W parts list, the 4516 sideplate is #108600000. The later version 4506 (R1) has the same number while the early 4506 version is #106990000.

Any idea what the difference is between the 106990000 and the 108600000? I see the 106990000 listed for sale in several places, but am having a hard time finding the 108600000.

You might give Numrich a call. They have the sideplate for the 4506. I believe OEM part# 10860 is the one you need. Numrich doesn't list the S&W part number in their parts listings. The one listed below may be the correct one, but you'll have to confirm by phone.

What's up with the 3rd Gen sideplate assembly?
