1911A-1 Hammer

[McGee]

My Springfield Armory 1911A-1 has an extra, small sear notch just before the safety notch. I think it was a manufacturing defect, and I contacted Springfield Armory but received no response. I've attached a picture with an arrow indicating the additional notch. A normal hammer is pictured beside the Springfield Armory hammer for reference.

I first noticed that touching the trigger caused the hammer to fall from what I thought was the safety notch. However, I learned that to engage the actual safety notch required pulling back the hammer back a little further. I disassembled the gun and removed the hammer for inspection.

The safety notch functions to catch the hammer if it accidentally slips when thumb cocking, and I would never use it for a carry position, but I don't like the "ambiguous state" with this hammer position and plan to replace the hammer.

I'm interested in other opinions.

all i can say is, "call S/A, as they are slow to respond to emails"

and next..

Springfield designed that hammer for a reason....

if you replace it, you may be disabling some sort of safety type of reason..???

also too, if you replace that hammer, just remember that if you do/did disable any safety feature, and you have "some sort" of accident..??

you are on your own, you cannot blame S/A.....

@xdman may be able to chime in on this. He probably owns every SA firearm to date.

SA has a warranty, contact them and send it in for adjustment/repair

Does the gun function ok, if so, what’s the issue? And why would you take the hammer out, it’s not needed for normal take downs and cleaning.

Perfectly normal for SA. My Ronin is the same way. SA calls it the safety stop.

I see that others have hammers with this additional notch. My first experience with 1911 style pistols was a pair of Series 70 Colts I purchased in 1976... a 45ACP & a 38 Super Auto. Of the may I've owned, this is the first with the additional notch. My preferred hammer is a pre-1939 wide-spur, checkered. Today, good ones are no longer available at reasonable prices. The reproductions don't seem as nicely made.

I purchased a satin nickel Tisas 1911A-1 Stakeout, which came with a 9mm barrel & magazine and a 38 Super Automatic barrel & magazine. It featured a commander style hammer and beavertail grip safety. Preferring the classic 1911A-1 appearance, I swapped the grip safety and hammer for mil-spec style.

I installed a satin nickel Armscor 4533MN-A hammer and Wilson Combat "Bullet Proof A2" sear. I liked the hammer so much that I purchased the same, but black oxide, for my Springfield Armory 1911A-1, also pairing it with the Wilson Combat sear.

I really disliked the additional sear notch on the original hammer. However, it did not affect normal functioning but served no useful purpose.

I carry "cocked & locked." but when stored, while locked in a gun safe, the hammer is lowered over an empty chamber with a full magazine inserted. I never lower the hammer over a live round, because I cannot think of a good reason for doing it.

Pictured below, the new Armscor hammer is on the left.
