In view of the recent tragedies at Sandy Hook and at the Boston Marathon, not to mention the many incidents of thuggery that occur every day in our cities, I've adopted the practice of carrying lightweight but useful "just in case" tools when I'm out and about.
Here's what I've come up with:
First, because I'm lucky enough to live in a state that trusts its law-abiding citizens with discretely carried firearms, I carry a lightweight .38 special revolver, alternating between this 642 and a 442, for either night or day use. I want any potential attacker to be fully aware that I have a gun when it's drawn, and I want it to be visible.
The flashlight is a tiny Four Sevens Preon P1, powered by a single AAA battery. It has three levels of power from quite dim to very bright; its highest setting puts out an impressive and potentially blinding 70 lumens with a run time of 40 minutes. At the low setting, it's also useful for reading restaurant menus in dim light! I carry it routinely clipped in my shirt pocket; it weighs practically nothing.
Spare ammo is available in a speed strip carried in a Dillon ammo pouch. The six additional rounds give me a total of 11 shots if I need them.
A cell phone is a must if needed to call 911 or a tow truck from wherever you might be. Mine is strictly for making phone calls and keeping appointments.
An ace-in-the-hole that I often carry is a tiny backup .22 mini-revolver that could provide a nasty surprise to someone someday. Some gun is way better than no gun. It fits in a pants pocket and is totally unobtrusive.
Always carry a knife. Mine is a Benchmade Elishewitz button-lock model. Useful as another backup weapon, and for such things as cutting seat belts. I have used it for that to extricate a lady pinned in her car with a seatbelt that could not be released.
A pen should always be with you. If you need to write down a license plate or phone number, or an address, you have it.
I have carried a GI pocket knife since my Army days. It incorporates an awl, a screwdriver, a can opener, and it's just the thing for popping the cap on a bottle of Heineken.
If I'm in my car, I will have a GPS available to guide me in unfamiliar locales.
Not seen here, but also necessary - photo ID, concealed carry permit, the name and number of a self-defense lawyer, my U.S. Concealed Carry Association Shield insurance policy phone number, and some cash, including about 3 dollars worth of quarters for parking meters.
Am I paranoid? No. I have not a lot to worry about with this equipment on me; the only other necessary thing, in my opinion is alertness - never in anything less than condition yellow.
Your mileage may vary - You might have other items or special need devices. What do you think?
