At one of my jobs, managing a combination convenience store/pizza parlor/game room, assistant manager, and PT bartender, and cover charge booth attendant at three night clubs and a strip club, and VP of security, I carried a LLama .45 ACP, 9mm Luger Tokerov, (or S&W J frame .38 Spcl/357 Magnum revolver), in a SOB and shoulder holster, and a Chrome plated Locerin .380 in my fanny pack, (along with extra mags for the pistols. company policy was "If you're on company property, you
will be armed." I was also part owner of the company, so it was legal for me to concealed carry on company property.) a Old Timer 7OT or Buck 460, and roughly 10 pounds of keys (over 350 keys on my belt. I had keys to every door at every company business location, and all storage location, plus my personal house and vehicle keys), a Mag light mini-Light (double AA batteries) or a triple D cell Mag light, from 1990 to 1994 and 1995 to 1999. From late 1999 to 2007 I didn't need to carry a pistol or revolver, and had a lot less keys after we relocated to Nevada, Florida, and Idaho. (Yeah, it was a PIA flying from ID to FL and back, or driving to Nevada from Idaho and back.)
According to the scale, I was toting an "extra" 30 pounds every day, before the move to Nevada.
I haven't found what is "too much" yet.
