Authenticate a part on a 70's era Colt GCNM

Just bought a "presumably all original" gun in excellent condition.  Were they ever offered with a checkered, matte finish (similar to the finish on the underside of the frame) slide stop or was this non-original part "omitted" by the seller?
Thanks guys.

Is the term "presumably all original" yours or the sellers? I'm extra cautious when buying used guns, but if that was the sellers wording I would be concerned that he knew something that I did not and was covering his tracks. I am OCD though.

I purchased a Series 70 Gold Cup new around 1978.  My recollection is that the slide stop was Colt Bright Blue like the rest of the gun.

99% sure it should be high polish blued. Not matte.

A checkered slide stop on a 1970s Gold Cup means you were sold a story. A story about false originality.

Is there any difference between the parts that go in to standard Series 70's and GCNM guns, now that I am apparently looking for the RIGHT OEM part?

[size=30]Colt Slide Stop 1911 9mm Luger, 38 Super Matte Blue  This is an original factory replacement part from Colt. Factory replacement parts are manufactured with the same specifications and are made with the same material as the original parts.[/size]


My GC 45 1970 model is  polished blue.  # 70N4663X  .

To the best of my recollection, my series 70 Gold Cup that I bought in the 70's, had a Colt royal blue slide stop. I used this pistol for bullseye pistol matches. It wasn't up to the job, even after a trigger job. IMHO only collectors look for all original parts. Of course, if the asking price was higher than normal, because of the "all original" claim, then you definitely have a legitimate squawk. Does it have the tiny spring on the sear and collet bushing?

Mine is polished “Royal”;blue like the rest of the gun.  During the 1970sand 1980s Colt was using slidestops that had longitudinal serrations.

Probably been re-barreled and they fit a new slide stop.

Greetings,

Buy a genuine Colt part from Brownells.

The slide stops, in recent years, have a number stamped on the inside.

"1" is for 45 ACP
"2" is for the 22 Ace and 38 National Match
"3" is for the 38 Super, and, I think, the 9mm

There have been additional numbers and I cannot say for what models.

An original slide stop for the Gold Cup should have a ground pin measuring 0.200" diameter.

Cheers,

Dave

the 1974 GCNM that I just bought has M2 stamped on slide stop pin supposedly it was what came on the gun but I starting to think this guy forgot what has been done to it sense it was new.
