Gun writer James Tarr reported his evaluations of two of Springfield Armory's 1911 pistols (the Garrison and Operator models in the August 2022 issue of Firearms News where he stated that the slide serrations on these two pistols have the "original angled type". I don't think this is correct because the original 1911 pistols, as far as I know, came with slide serrations that were not "angled". My early 70's Gold Cup has angled serrations but I'm curious as to when Colt made their first 1911 pistols having angled serrations. Anybody know?

You'd be correct.

Springfield starting using the angled serrations in the mid '90s, at least that's when I believe I got my first "Mil-Spec" marked model with them.... After a couple pre-G.I. early '90s models.

I was always under the impression Colt didn't start doing this until the Series 80, NM and Enhanced models. I could be wrong.

Because, frankly, I guess I never paid attention. Even after owning over 40 1911s by various makers.
 
Ain't much you can do to a 1911 to change it's looks from all the other 1911s out there, except for grips, slide serrations and rails. Skeletonized triggers and hammer, and lately slide cuts. It's all good.
 
That is a post-war conversion or ACE slide with slanted serrations to complement the Gold Cup.
Do you know where the rest of the Singer is?

All of the parts of the Singer were brought out and put on the table after we searched for whom the manufacturer of that receiver could be. I have never seen one, and did not know whom SM was. And I wanted pictures. The owner has the complete, and from what references I saw later, original Singer 1911. That day however, he had installed the ACE upper which he had purchased from the last owner of his Singer 1911. He had purchased them together. I got to shoot the ACE. It was designed to mimic a 45 ACP recoil. The ACE 22lr upper did significantly increase the recoil, above that of a straight blowback 22lr. However, the recoil of a 45 ACP is still greater. Both of these things are collectable. Based on a web search, the Singer is orders of magnitude more valuable than the 22lr.

So, I saw a unicorn.
 
I had a very early Springfield Armory M1911 A1 that had the slanted serrations on the slide.

Currently two out of three of my somewhat newer Colts (Lightweight Government Model and Commander), have slanted serrations while one (Government Model), has the vertical serrations.

I had a Colt Conversion on a Gold Cup which was troublesome and had the Murphy Factor of not being set up in the caliber I wanted to shoot on a given day.
I ended up with an ACE pistol and the floating chamber does give it a bit of a bump but it is not as accurate or as reliable as the Nelson Conversion I leave mounted on my least-used Caspian .45s frame.

Yes that is a correct use of "orders of magnitude."
A complete, original, and excellent Singer is worth probably 100 times the .22 conversion.
Two orders of magnitude.

Mr. Tarr is clearly incorrect - if by “original angled type,” he’s referring to the serrations on “original” Colt 1911s and 1911A1s. Here’s a 1915 Colt model 1911, no angled serrations:

And here’s a well-known comparison picture of post-1924 A1 modifications added to the 1911 design … No angled serrations either:

Your experience probably explains why I see lots of other 22lr conversions, such as the Marvel, instead of Colt ACE uppers. Still, everyone has issues with 22lr pistols. Recently shot a 2700 match and there were 12 competitors. The match director mentioned at the end of it, how remarkable it was that with 1080 .22lr rounds (90 X 12) blown down range, no one had an alibi! We had more alibi's during centerfire and 45 ACP than with the 22lr. And that is remarkable.

at this range, when a shooter calls an alibi, a Safety Officer comes and verifies the alibi and collects the alibi round. Which is then presented to the match director, who then drops it in this sectioned soft drink bottle. As it can be seen, 22lr rounds are the least reliable rounds in competition. You can see multiple strikes on some. And this mirror's my experience. I am leaving my M41 in the safe and using a Ruger MKII as that pistol has a more powerful ignition system and therefore I have fewer failures to fire, or stove pipe jams. Weak ignition leads to weak powder combustion and that results in failures to eject.

Aggravating my situation is that I purchased several cases of CCI SV during the Truimp administration, and I am not willing to pay for Eley Pistol Tennex. Those shooting the expensive pistol match ammunition have less problems than I, when I am firing CCI SV. It is remarkable when I can fire 90 rounds without a failure to ignite, or failure to eject.

The shooting community is largely ignorant of the importance of strong, powerful, and consistent primer ignition. It turns out good ignition is not only critically important for function, but also, accuracy at long range.

I can say, wish I had found that Singer M1911, but I did not. But I did get pictures.
