Tuner...thanks for the drop-in hammer!

[Malikovski]

Finally had time to get to work on my (self-inflicted) malfunctioning 1911, thanks to the replacement hammer kindly donated by Tuner to the cause of remedying my WECSOG ways.

First putting all files, stones, and other implements of destuction far away...I used the Colt hammer, an unused WWII sear, Caspian Arms disconnector, Colt sear spring, and a Wilson Combat pin set which is supposedly made to the max spec sizes for 1911 pins. All the parts fit nicely, function and safety checks fine, slide drop test fine, hammer push off test also fine, and although the hammer can still wiggle in the slot, it no longer falls off the sear if pushed and wiggled.

Trigger pull is of course heavier than with the buggered up, oversquare hammer hooks and round-nosed sear, but I think I will let the new parts break in by shooting a few hundred rounds or more before I evaluate. Since I am rehabilitating the pistol to be a carry piece, I will probably leave it alone. If I want a two pound trigger, I'll carry my revolver

Thanks again, Tuner, a shepherd to your people you are.

Hammer Shepherd

Malikovski, the hammer came out of a fresh Springfield GI Mil-Spec that had seen very little use. The Colt hammer that I had was well-used, and looked to be a little "iffy" so I sent the Springfield hammer instead. Glad it took care of the problems for ya.

 

[Malikovski]

You sent two hammers, one with identical markings to my Springfield, and another, which I assumed was the Colt hammer you referred to. The back of that hammer was modified, but otherwise I didn't notice any wear on the park and assumed it was unused.

Did I just put the "iffy" part in my gun?

Iffy

No. Sorry...I forgot that I included that hammer, and it is a Colt. The one that I had in mind was a pre-Series 80 with a captive half-cock notch.

 

[Malikovski]

Ah good. I didn't think it looked iffy, but I ain't the expert around here.

Is there any problem using a series 80 hammer with a series 70 firing system (e.g. the way my pistol is now)? I assume no, since my gun came from the factory that way, but at the same time the captive notch must have been there for a reason...

Hammer

No issues. The only difference is the half-cock notch is actually a quarter-cock shelf...and your GI Springfield has the same design as the Series 80 Colt's. Keep a sharp eye out for hammer follow and for the first outing, load two rounds per magazine for about 10 mags to make sure it's not gonna go full auto on ya.

 

[Malikovski]

Oh...I thought series 80 had a firing pin block.

Perhaps I ought to start reading those shpo manuals I ordered...

It does, but it doesn't involve the hammer. The hammer from a WW1-era Colt...or from a WW2-era Remington Rand or Ithaca or Union Switch or Singer or Colt will interchange and function in a Series 80 pistol...or a Springfield.
In fact, I've got a wide-spur hammer out of an Argentine Sistema in an early 90s production Springfield.
