Light Trigger
Al,
I'd subscribe to the "Bubba" theory, or at the very least,
the wrong sear engagement surface on the hammer hooks It sounds like the hooks are cut to make for a negative engagement, or the force of the mainspring is trying to push the sear out of engegement. As opposed to a neutral or positive engagement, where the mainspring works to pull the sear to the bottom of the hooks.
At any rate, your trigger sounds a little risky, and just a little
wear on the surface could push it over the edge, literally.
many don't understand the inertial forces at work in an autoloader's hammer/trigger operation, and with these
"razor's edge" engagements, all it will take is a tired mainspring
to bring on some grief, or at the very least, acute embarassment.
I'm not familiar with the Makarov, being more of a 1911
specialist, but the same principles will apply.
Take care, and keep safe...
