COLT gold cup nationnal match

If you are using full power ammo, just make sure the recoil spring is suitable. The recoil spring on early guns was DEFINITELY a target weight spring, and with age, may have become "weaker" still. Some guns originally came with two springs, one for target and one for hardball ammo. Firing full power/hardball ammo with the target spring will work, but it will really pound the gun. People above responding "no problem" are correct, that the gun will work, but will also gradually pound itself to pieces if it doesn't have the correct spring.

I don't know what springs come with the newer guns. Springs are really cheap to replace, about $5 to $10. So if you are firing full power ammo, just put in a new spring.

Also, not all Wolf ammo is loaded to max. Some of it is geared to IPSC major, which in 45 is less than full power.



The above is not speculation. My dad had a Gold Cup National Match, either Series 70 or maybe earlier, and even had the Colt 22 conversion for it.

about the NM Series 70, I still have one with also a Ciener .22LR conversion.

A superb piece with much likely a better trigger pull than the new series 80 trigger system.

X2 fregarding recoil spring selection.

This gun is a pure pleasure to shoot and I reserve it for target loads and .22LR.

I use my SA or Kimber for hardball equivalent.
 
I shot a 70 series gold cup 45 for about 12 years and put over 50,000 round through the gun. I have shot lead, FMJ, jacketed and never had a single issue. I changed the barrel once. Had some custom work from Dlask in Burnaby. Fine guns.
 
Colt Gold Cup National Match

I've had a couple Colt Series 70 Gold Cup National Match and a Series 80 GCNM pistols over the years. The only thing I found that had to be watched is the cross pin that holds in the rear adjustable site sometimes tries to work itself out over time. Other than that I would say they are set up to take standard .45ACP loads just meant to deliver them with a tad more accuracy that the stock government model. That is not always true however.

I have a Series 80 Gold Cup NM and I've been able to shoot a wide variety of factory loads and reloads with out any problems. I have to agree with SandRoad about the pounding that the gun may take. I definitely notice an increase in felt recoil due to the increase in energy directed back by the slide with factory loads compared to some of the reloads I run.

I'm thinking I should look into getting a couple of new springs to match whatever load I am running just to be on the safe side.

You may want to install a ShokBuff or similar polymer buffer on the spring guide to reduce frame battering.

Some people think that because the GC is a "match" or "target" gun, it is more fragile and needs to be babied. But it is made like all other Colt 1911s except for the greater attention supposedly paid to its assemble and fitting.
I also replaced the stock spring with an 18 pound one.

I did notice the barrel to slide fit was tighter on my GC (sold). I didn't like the Eliason rear sight because its hinge pin (split pin) kept on loosening. I just punched the center of the pin on both sides to tighten that up. Bomars on my other 1911s actually worked better for me.

It was probably mechanically a little more accurate than the run of the mill government models but because of the wide trigger, I couldn't shoot it as well as regular gov't models.
 
Just bought one (Model 05070x) and put about 500 rounds through it so far.
Came with 2 springs, the green one is for lighter loads.
Now the green is just cheap paint and I can see it wearing off easily with use and cleaning.
Other than that both springs look the same and feel the same.
Once broken it who knows "how they will feel"
I'd say you have no idea which spring is in a used gun, so just replace it.
The manual says the lighter one is for semi wad cutters????
Which in my opinion is meaningless bc you can load them to the same pressure as ball.
You also get 2 mags a 7 and 8. The 8 is for wad cutters and useless.
I need a certain amount of reliability for IDPA so I love this gun for that.
It is not reliable enough for a field or defense gun.
 
Later Gold Cups are fine for ball, but the early 70 series had a "lightening cut" of relatively large size in the slide as well as light springs. My wadcutter gun is built on one and I definitely would not fire ball or anything close to it in it.
