There's Colts and then there is everything else!
The Colts...........
The Colts range from .22 rimfire to .357 mag. Some are target guns, some are carry guns. They are all 35 years of age or (much) older.
The Others.........
Much more diverse, again ranging from .22 rimfire thru 9mm, .357 Sig, .40 S&W, .44 mag, to .45 ACP. With the exception of the Ruger .22 the rest are for "serious social encounters". Again, other than the Ruger which is about 50 this year, these are all fairly new.
You never know when you might need a good "spoon" or two!
