    The 642 has a clear finish on the cylinder that wears off. Does the 640 Pro have the same finish, or is the gun without a finish? Thx.

    It's stainless steel and has a semi-polished finish but not one that can wear off. The 642 is coated and can chip/wear. On the 640 there is nothing but steel so you could scratch it but that is it.

    Similarly, you could polish it, bead blast, soak it in hoppes, or bang it against a wall without too much trouble :D

    The 642 FRAME is coated, the stainless cylinder is not.

    All aluminum frames since SW has been making aluminum frames have been "coated" or anodized. This does wear faster than bluing as a rule and always has. They're tools..

    I love my S&W 642, but didn't like the frame finish...




    Had Robar redo it in NP3 Plus... and very happy with it. When they stripped the anodizing, they had to redo the serial number due to how light it was after.

    There's not much you can do with an Aluminum Alloy revolver like the M642 other than anodize it like on the M442. The M640 however is Stainless so it requires no additional finish.

    (yes, yes I know the cylinder isn't Aluminum!)
