I'm looking at a used 640 CAH2xxx for $389.95. I'm not sure if this is a new model or 640-1 as I can't tell by serial number. Is this price typical for this gun used?
The S&W model 640 .357 magnum was made between 1990-1995,
and the book says NIB value is $360.
Also, the 640-1 was made from 1996 to 1999; and its stated NIB
value is listed as $425.
The gun you are looking at (with a CAH serial prefix) was made after
August of 1994. Sorry, but the Standard Catalog Of Smith & Wesson
isn't more definitive. Hope this helps?
Well the 640 was a .38 Special made from 1990-1995
The 640-1 is a .357 magnum produced 1995-1997
The 640-2 is a .38 produced 1997-1999
The CA serial number prefix seems to have been only used in 1994.
My guess is what tyou are looking at is a .38 special 640. Which is very nice because it is made on the slightly smaller J frame whereas the -1 & -2 were made on the slightly larger J-magnum frame.
The biggest real difference is the 1/4" barrel length. The 640 had a 1-7/8" barrel while the -1 & -2 had the 2-1/8".
Also, if you open the cylinder and look at the yoke you can read the model number.
