Lanyard loop straight out the bottom (hammer spring sits down in the upper/cup part of the lanyard loop?) Or sticking out the side and the lanyard loop is attacted to/part of the pin that holds the hammer spring plug/cup in place in the frame?
The first one is factory. No idea who came up with the idea for the second style but you see those on used/surplus pistols imported from overseas after the military/police using them there get replacement pistols.
Never saw on on a new pistol that was bare metal. They are black, like the rest of the frame/slide. If you buy a new one (I actually prefer to have them on my CZs) then they arrive in the little baggy with the black coating on them, too. The plastic framed CZs use a plastic lanyard loop/hammer spring plug, but it sticks out of the bottom of the frame, too.
