Very new to this forum, hope you all don't mind my chimeing in but really love my three J frame revolvers.
Have a 640-1 chambered for 357M although it only gets 38 wadcutters sent down the barrel. Serial number is BUJ05xx but I don't know the year it was made; has unmarked rubber grips so guessing their Hogue; barrel length is 2 &1/8 inch. Also has pinned front site but maybe that is for all of them, I don't know. Being a stock gun the trigger pull is very smooth, never feeling heavy to me. I keep looking for another nice condition 640 but in 38 special. Thanks everyone for this great thread on the 640 Smiths.
