A Model 15 was my first issued handgun in the USAF. An interesting story about how the USAF ended up with the M15-Gen LeMay was a shooter and wanted a revolver that everyone could learn to shoot accurately (vice the worn out 1911's in the inventory), although he wanted a 45 cal for his aircrews, which he never got. The M15's were standard issue for aircrew, Security Police, and OSI Agents through most of the Vietnam era. OSI changed weapons a couple of times in the intervening years but the M15 was the standard handgun for the rest of the USAF until the M9 was issued around 1986. They were a workhorse and a lot of them had 250,000 rounds through them or more during their working life. Defense Property Disposal Agency takes weapons from the supply system and disposes of them as per policy. If the weapons are serviceable and could be legally handed down to other military units, federal agencies, or state or local government they could be transferred. If they cant be transferred they would be decommissioned (destroyed). Once in the state or local system they could be subject to trade-in and wind up on the market but highly unlikely. We closed a lot of bases in the UK in the 90's and a lot of stuff got destroyed but regargless there was no where in the military system for those M15's and darn sure was no place for them in the UK! Such a sad sight.
