No dash number, no "M", it must go back to Smith for the recall.
I have an early release 681 too and I luv it
I also called S&W about this recall and the technicians said that not all early release weapons suffered from this issue and that a simple check would verify if you need the recall work done. He also told me that you must run the serial number on the bottom of the pistol grip to be sure as the other numbers are not "consistent" and that having the recall work done may mar the finsih of the weapon slightly so don't do it unless you need it.
The simple check the told me to do was to 1) dry fire the weapon and continue to hold the trigger in the fully pulled position. 2) while still holding the trigger, pull back the hammer. If it catches on the busing while pulling it back, it needs the recall work. If it pulls back smoothly with no interference, then they said not to send it in as it is not suffering from the issue addressed by the recall.
Hope this is helpful to anyone 'on the fence'
Here is my 681 with S&W combat grip installed.
