Odds are, you'll never need the first gun, but you don't carry a gun for probabilities, but possibilities.

642's were made for front pocket carry, then the primary is no big deal. Two gun carry is no big deal or strain. A 3" .357 and a 642 for example are a great combo. The primary can use the 642 ammo. One of my favorite summer combos is a 6906 and a 642.

The BUG is insurance, it's up to you to decide if you want to go to the trouble of it or not. I'm into being prepared to the hilt, but that's just me.
