1) Get a HK P7M8 .
2) Have it hard chromed.
3) Put some Nill Grips on it.
4) Post the pictures.
Beat me to it (except I recommend getting a much cheaper PSP/P7). That is exactly my plans for the one I just acquired.
Barring that, a few suggestions:
1) AMT Automag III - .30 Carbine / Easy to find, not too pricey and already stainless
2) Beretta 92FS INOX - again with the stainless
3) CZ75 as someone else has mentioned - can be had with stainless
4) Browning Hi Power
5) Schofield or 1905 Colt splendid idea.
6) Webley MK VI revolver in .455
7) Get more engraved pistols!
8) Replicate guns from movies you like. Like Pulp Fiction? Get 1911A1 Auto Ordnance .45 ACP pistol chromed w/ pearl grips and a Star Model B 9mm chromed w/ pearl grips (maybe ivory instead?)
I'm not too jazzed with new stuff out there - all different flavors of the same thing. Nothing exciting at the moment.
