I need help finding this particular kind of D-ring. Is there a name for this? Having trouble finding the real thing, although I know it exists. I'm working on making the Fourpounder from Deathloop.
The D-ring would be in the neighborhood of 3cm wide and the post about 1cm in diameter. Pretty small, you can see it here relative to the rest of the gun.
Pistol lanyard loop. Many older military revolver and pistols had them as an attachment for a retention lanyard. Still a feature on most military sidearms.
