Which is the standard AK FCG design?

[Buckshot Barry]

I just noticed a major design difference between my Arsenal SGL-21 and Draco-C Romanian (not Tapco) fire control groups and was wondering if this is a design difference between the AKM and AK-100 series or an Arsenal design or something else.

When the firearm fires, the hammer is pushed to the rear. If the trigger is still in the rear position the hammer is caught by the disconnector. This requires the trigger to be released for the hammer to clear the disconnector.

Now here is the difference. The hammer only goes up a small fraction of an inch on the Draco after it clear the disconnector. When pulling the trigger to make the second shot there is resistance between the trigger and main spring AND the disconnector spring must still be compressed because the hammer contacts the face of the disconnector.

On the SGL-21 after the trigger is released getting ready to make the second shot, the hammer is raised much higher completely clearing the disconnector. When pulling the trigger there is only resistance with the main spring and the disconnector spring does not have to be compressed.

The hammer is noticeably higher on the SGL-21 when cocked requiring the bolt to be press down during re-assembly when putting the bolt back in to the firearm after cleaning.

Which is more like a real AK-47?
