I recently found this gun in a closet after my grandmother passed and know very little about it. It is a s&w 44 and the serial # is 489X any info would be great. It is a beautiful gun with ivory grips!
Assuming you took the serial number from the bottom of the grip butt, SN 489X would make it a .44 Hand Ejector 1st Model (Triple Lock).
Serial numbers ran from 1 in 1907 to 15375 in 1915.
Caliber options in .44 were 44 S&W Special, 44 S&W Russian and 44-40 Winchester.
These are highly collectable and valuable guns.
A picture would be great.
