Security Six - how much hammer/sear engagement is normal?

[georgiaruger]

I have a 1979 vintage Security Six that was purchased new in 1980 and sat unfired until I bought it in 2011 from a colleague who had originally purchased it. So, it's still a very young gun.

In noticing that the single action pull is very light and has hardly any trigger movement at all (not that I expect much in the first place), I looked down on the hammer/sear engagement when cocked and noticed the amount of the sear being engaged by the hammer is very very little. Like probably less then 5% of the exposed face of the sear. So little that I am a touch concerned about long term wear with so little edge of the sear being asked to carry the hammer's springed load.

What amount of sear face engagement is normal? Is this something easily adjusted (if needed).

One simple test, does the hammer push off? In other words, cock the hammer and apply thumb pressure to the back of the hammer. If you can't push it off the sear, I wouldn't sweat it.
There's no easy adjustment unless you really know what you're doing.

Thanks.

I did my first dis-assembly this morning (which is indeed very easy) to take a closer look at the trigger's sear face and matching mating surface on the hammer. I saw the the hammer has a very small lip/notch cut onto it that catches on to the trigger's surface when fully cocked. So it now appears to me this is functioning as designed. (I guess I am just always amazed at just how little working surface/contact area there can be in a critical element like the sear/hammer interface of a firearm)
