There have been some changes to "the plan" from the fience. I have 3 groomsmen, and my brother is officiating the wedding. She said I am to oly get 4 guns, and I con't leave my bro out... Which makes sense to me. I really wanted a souvinier as well, but I guess I can always replicate at a later date. Here are my options as I see them:
cobra derringer nickel/cherry ~$140
Pheonix arms HP22A ~$125
KelTec PF9 ~$225
Cabelas (or other) cap/ball BP pistol ~$185
Surplus p64 ~$160
So the issue with the P64 is that the laser etchign or engraving will probably look bad on a 30 year old gun with a lot of wear on it. Taking all 4 apart and re blueing them would be complicated with all the parts that are likely to break, so I think they may be out.
The ball&cap BP pistols are sweet looking, but highly impractical. The price is enticing though.
The HP22A is no doubt a cheap firearm. The company stands behind their mediocre product, and the are cute little pocket guns that cost nothing to shoot.
The KelTec is out of the price range. I don't think I can swing 4X that plus engraving.
the derringers are seeming more and more cool, and also classy.
