My understanding (internet) is polished nickel is one process and matte nickel a different process. That being "electroless" for the dull finish and "electrolysis" for the bright finish. Is this accurate or dated info? Is the dull finish durable enough for the average user who cares for but doesn't baby the 1911? Must special care be taken when cleaning the matte nickel finish? The reason I ask is I'm looking at two different manufacturers 1911s, one in the matte nickel (basic G.I. Rock Island) and the stainless Springfield Mil-Spec. Cost difference is 100.00 (542.00 / 642.00). I realize most folks would opt for the SA, however, I like my Rocks just fine and the Rock has the standard low profile sights which I greatly prefer. There are other considerations however this is my basic one currently. I'm just curious as to the Rock's matte nickel finish being worth a hoot or if I see one, run and don't look back. Thanks.
