First off, welcome back LSP972. Glad to hear you're doing well.
As others have already said, I'd feel good with a single stack 9mm like a Shield and a J-Frame. I'd consider ditching the second J-Frame and in it's place carry two spare Shield magazines.
LSP972, you suggested carrying a 342 vs. a 442/642 for the extra weight savings. I've owned a 642 for years (actually on my third as I tend to sell them, kick my self for doing so and replace with another) but I've never actually shot a 342. While the weight savings is noticeable, is the felt recoil also very noticeable when going from a 642 to a 342?
