Interesting thread...
When I was stationed at Lowry AFB, CO in the 1960's, we had some hi-speed 150 grain .38 ammo that I think a unit NCO bought in Denver. It had RN-FMJ bullets. I think I also saw those M-41 rounds. We had a few .45 autos, and I often carried one, in a Jordan style holster that I had made for me on leave by a shoe repair shop in Dallas. The store owner was into holsters and made about as good a rig as Don Hume did.
We had mainly Victory Models and a few Colt .38's, with investigative personnel having Cobra or Detective Special snubs with hammer shrouds. The M-15's were in short supply, and went to officers and senior NCO's. One officer carried his own M-14. (S&W .38, not the rifle.)
We had .30 carbines on expanded security alerts, and M-12 Winchester riot guns for prisoner escort.
All USAF M-15's that I saw had the target hammer and trigger. I heard that Gen. Lemay thought those would up the qualifying scores. Personally, I'd have preferred the standard hammer and trigger.
I guess that if it didn't have The Lock and MIM parts, I'd be interested in buying a commemorative M-15. I've never bought one because I preferred the .357 capability of the M-19 and later, the M-66, and the enclosed extractor (barrel lug).
I wish that Saxon Pig would read this thread and see what use of Plus P ammo did to the USAF .38's. He maintains in other topics that Plus P doesn't amount to much. I think that some Plus P is hotter than he thinks.
If I had to be armed with a .38, I'd unhesitantly choose an M-67. It'd have all the goodness of the M-15, plus the rust avoidance of stainless steel. I thought that the M-67 should have been issued to aircrews, who might be unable to oil their guns until rescued, maybe days or weeks later, under all sorts of environmental conditions. But I guess none of the bureaucrats in the Air Force cared.
I do know that some Air Rescue personnel in Alaska received S&W .44 Magnums after a crashed airman was eaten by bears and they were unable to help, as they were unarmed, or had just .38's. This was in an Air Force magazine in the 1960's. I was amazed that they didn't have suitable rifles on the rescue choppers.
