I took my 1911 with me twice yesterday. Somehow, I managed to resist the orbiting NRA Mind Control Ray. Here is a more or less stream of consciousness set of impressions.
1. The holster (Dragon Leather Works Quantum) is really, really good. Specifically, it's rock solid, and holds the pistol absolutely immobile. Sitting down, standing up, leaning on the railing of the Congress Street Bridge (to see the bats, natch) - the pistol didn't change its position at all. This is in great contrast to the first time I CCW'ed - my crummy holster that time ended up slipping down inside my britches, so I was always worrying about it.
I was also always messing with it, and as Tam likes to say, stop messing with your gat. This holster meant I didn't want to. More on the holster itself in a later post, but if you're new to carrying, run don't walk and get a good, stiff holster with strong belt clips. Srlsy.
2. I changed a couple times before I left Forward Operating Base Borepatch. Some of my favorite Hawaiian shirts print pretty badly when I bend over - the shirt catches a bit on the grip and it becomes obvious that I'm carrying. Heavier fabrics seem to work better - either they resist getting snagged, or the fabric is heavy enough to drop off the grip.
3. I didn't have a round in the chamber. I was a bit nervous, it being really the first real time and all. Obviously, you carry a pistol for the unexpected, and so this was way suboptimal. Once I'm more used to this, I expect that cocked and locked will be the norm.
4. The laws in Texas are seemingly subtly different from those in Georgia. My guess is that the first rule is "Don't cause a problem for someone else", but I actually asked a couple guys in the office what I should know. The two answers were "don't drink if you go into a bar" and "Don't go places where there are the '30-06' signs posted" (this is the state law that lets private businesses ban firearms). This bit was where the solidity of the Quantum holster came in handy - since I wasn't worried about the piece itself shifting, I could devote all my attention to keeping myself as much out of legal trouble as possible.
5. It seems that "Common Sense Gun Control" consists of a lot of strange and unexpected additional prohibitions that most people are unlikely to know, especially if you are - like me - from out of state on a reciprocal permit. Probably I'm being nasty and suspicious here.
More impressions later, but today was a thousand times better than the first.
