Good Smile Company just released a new series for its “Metal Charm” line up. This 2nd series, with Nanoha as the 1st, will be based on the Fate series under the name “Fate Metal Charm Collection” ^^

The first release from this new line up will be Saber’s Excalibur, “Fate Metal Charm Collection #01 – Excalibur”. It’s scheduled for November 2008 release for 2,800 Yen. I think GSC’s did an Advanced Sale on this during Comiket 74.
I don’t know about the Thompson Cotender gun, but maybe it’s from Fate/Zero? Not very familiar with the series’ story ^^;
