Yeah the police specials are Matte black, where as other Beretta 92s can be matte black, blued, or duo tone black/silver.
$430 is a great price, I wish I could find that deal! The best price I've found so far is $505 shipped, but then there is the FFL dealer fee, which I haven't asked about yet but is probably like $40-50 here in Cali. = (
I'm going to a gun store on Saturday to scope out prices, but if I remember I think the local one was selling them very closer to MSRP, like $600++.
But it is a great gun, you'll love it, I know I sure do.
