I live in Houston (native), and at 62, have had a Texas LTC since 1996, the year the license was 1st available, IIRC. I don't consider myself an expert, but after years of carry and mutli gun comps, I have a good idea of what works for me. I have carried many different handguns, the vast majority of which were autos. S&W, HK, Glock, XDM, 1911/2011, FN, Sig, etc. Like others, I base my EDC on what I'm wearing, what I'm doing, and where I'm doing it. Weekly bank day, for business deposits? I was jugged last year...followed from bank to a retail center, where I found my vehicle burglarized-glass smashed out, and an empty deposit bag gone. I also keep a P226 and a AR in my truck, so I'm glad I didn't catch the idiots in the act. Unfortunately, this type of thing has happened to me several times in the last 5 years or so, and has been more common in general, seemingly everywhere, but especially in blue cities like mine. So, on bank day, I go a bit heavier. Currently, my primary is a P365 Fuse w HST 124s, backed up with a 340PD w Speer 357 SB 135s. Sometimes I wear a (thin) level III vest. Around the house, or exercising around the neighborhood, I pocket carry the 340 PD. I also have a P365 I use when I need more concealment than the P365 Fuse affords. Mountains or backcountry?: FN 510 10mm with hot penetrators. There's a rifle in both of my vehicles: S&W sporter in the Tundra, and a Wilson SB 300 Blackout in the Toyota 86, both with Magpul D60 drums & Aimpoints. Watching vids of thugs walking up behind people and snatching their handguns out of their holsters, I have switched from open to thumb break holsters for strong side carry. I also have a Galco shoulder rig, for a back up or car travel, which I can set up for the P365, 340 PD, and others. Spare mag count ranges from 0-2, depending on my perception of risk.
