Hello all, I was cleaning my Ruger 1911 ( deep clean) and I started to study parts of it.
I have a new Remington spur hammer, which I eyed up next to the factory Ruger hammer. I took the hammer pin, and placed it thru both hammers so they could align as close as possible.
In lining them up, the full cock hooks are in identical places, however the half cock position is off quite a bit. Maybe .080 or .090. I didn't measure it, but I eyed it up. It is noticeably different.
Placing the Remington hammer in the place of the Ruger hammer ( keeping everything else the same, the half cock notch seems to keep the hammer back off the firing pin stop area, without the pressure of the main spring. It almost as if spring pressure causes it to back away from the firing pin stop plate.
I realize that hammers are fit to sears and vice versa, but why would the hammers have such different half cock positions? Also, are there variations in sears for 1911? The Ruger is a 70 series. Would an 80 be different? How about the Kimber ( Swartz) design?
Again, the full cock positions are dead on the same.
I have always wondered about the Ruger sear/Hammer fit ( along with any other mass produced 1911). I would think they are less than optimal for the purpose of speeding the assembly work.
Any insight to this? I have searched and come up with a lot of information, but not my answer.
Thank you
