my military experience was over 20 years ago, but the 1911A1s in the ship's armory were used every year for "familiarization" and "qualification" on the flight deck. Neither was worth a hoot, and Boot Camp was spectacularly bad - 5 rounds from a Colt Ace 22lr, and no opportunity to see if you hit anything. We DID have 4 Ruger Service Six revolvers, and I bought some 38 Special ammo to shoot one on the regular qualification date, which irritated my Chief to no end. He also had no explanation why the guns were there....
My Dept gives better handgun instruction, but that's to be expected. What is also funny is even that is far less than I got on my own over the years.
