Handles

Here is the solution to your delemma.
Put the names of all guns acceptable to you in a hat (Ruger, T3,Vangard, whatever) Pull out one name.
Now put all acceptable calibers in a hat, and draw one out. As long as you have what you want in the hat, and the manufacturer makes guns in that caliber, you should be happy. You could say that Fate brought you and your new gun together.

If you were hoping for a different combination than what you drew, you knew what you wanted all along.
