Mine have always been IMI manufactured
My first Desert Eagle fell 8000 feet in a 1995 plane crash. The frame was torques and the magazine could not be removed Magnum Research was unable to fix it. I guess it could have been used as a single shot

My HK PSP was in the same crash and still works just fine to this day . . . Love that German over engineering
My 50 caliber Desert Eagle has been with me for about 25 years now
My 41 Magnum Desert Eagle has been with me for about 20+ years now
I probably need to get them out and do some photos
Every Desert Eagle I have fired has been very accurate and Very reliable
The one idiosyncrasy of the Desert Eagle is that they MUST be fed FULL POWER ammunition to be reliable. Mile all love BIG charges of H110 powder. NO mid-range loads for these guns.
Also do not be shooting lead bullets in these big beasts
Somewhere in the moving boxes, I have a factory original leather shoulder holster that may have never been used. It needs to get unpacked and put in the For Sale area
