I was in from 1977-1981. At Lackland AFB for basic, it was what was then relatively new two story dorms with half of the lower story a covered exercise pad. The Upper level was split into two bays with open bunking, with the TI's office separating the two. (Of course, no personal weapons there.)
Tech school was at Lowry AFB, Denver CO, and the dorms there were modern four story buildings with two rooms sharing a connecting bathroom. They were exactly like college dorm rooms. I bought my first firearm there, a Ruger 10/22, in 1978.
My working base assignment was Mtn. Home AFB, ID, working on avionics for the F-111A. Dorms there were older 2 story cinder block style dorms, but they had individual bathrooms with showers, not a common shower for the entire floor. That's where I had my Marlin 336C, the Sears Ted Williams 20 ga semi-auto (took a lot of ducks on the Snake River with that 20 ga, outshooting a lot of my 12 ga, 3" Magnum shooting buddies.) In 1980, when I turned 21, I bought a Smith & Wesson Model 19 Combat Magnum with 4" bbl. That was my first handgun.
So one shotgun, one lever action .30-30, one .22LR rifle, and one .357 magnum revolver was the entirety of my arsenal while I was in the Air Force.
Cool. I was in from ‘81-’85. Lackland, Lowry, and Homestead. WCS on F-4 C and D. I didn’t buy any firearms, but regret it. It was Miami’s cocaine cowboy days, and the gun shops had lots of cool toys. A guy in the dorm pawned me jis H&K 91 a couple of times. I kept it in my wall locker. The reason that I asked about the dorms was that I recently learned the medicine cabinet in the dorms at Homestead were remove able. The setup was a bit like Lowry...a bathroom between two rooms. The medicine chest came out so that a plumber could get in the hole and work on the pipes. I guess a few guys knew about it and hid stuff in there. Nobody I knew had a clue.
Once at Lowry, I walked through the bathroom while the yellow rope in the adjoining suite was taking a shower, locked his bathroom door, went out his room door, locking it, and came back in my door. Had to go to CQ to get him back in his room. I guess it was a security thing, but it was possible to trap someone in there.
