Hi,
When comparing the 642 and 442, does the 442 require any additional maintenance due to it's finish? Is the cylinder more susceptible to rust than the 642? If I remember correctly, the frames of both are aluminum, but the cylinders are either stainless (642) and carbon steel (442).
Besides that, are there any other practical differences?
Thanks.
