I often have something I’d like to post but it doesn’t rate its own thread, so I’m starting this one…..it’ll be an ongoing thing, a place to put some random shop goings-on and maybe just some general commentary which will be, you might say, “editorial” in nature, in other words presented as opinion. I might squeeze in a few light product reviews. Not “official” reviews mind you, just things I might be using or trying out at any given time. Some of this won’t be current, necessarily—some of the content might be something I’ve done in the past. The first one is a Gold Cup I’ve had in the shop for over two years as a side project. I squeeze a little work on it in once in a while between work on “official” projects.
I have never cared for the Gold Cup. Opinion only, remember! I don’t want insult anyone’s favorite gun but even as a strictly target pistol, I think it has a lot of failings….. as a carry gun, or basis for one, even more.
Many of these shortcomings are shown in this first picture. The Elliason rear sight is world famous, for shearing the pin and falling off. I believe Colt has gone to a Bomar-ish sight now. The one here had the Eliason (pic is not of the actual subject pistol).
The fat trigger. I never was a great big Bullseye shooter I’ll admit, but I could never really feel any kind of advantage in it. The disadvantages are several. Holstering a GC in a holster made for a standard narrow trigger…. not good. The biggest thing is the trigger's weight (mass). Here again I think maybe Colt has gone to aluminum recently but it must be quite recent….. I have not seen one and this one had the traditional steel trigger with the big crooked slot to reduce the weight somewhat. I have comparative weights around here somewhere that I will try to include. I can’t weigh the original because I have already disposed of it, but they are relatively heavy. This is a big deal in a pistol that over the years has had a lot of people do trigger jobs—being a target pistol, people want light pull weights, right? The weight or mass of the GC trigger in a pistol that has been worked on for a light pull is a big safety issue, as it leads to to hammer follow caused by the trigger’s inertia. When the slide slams home chambering a round, the frame jumps forward and the trigger stays where it was, dropping the hammer and sometimes firing the gun.
I hesitate to even mention the techniques some target shooters used for years to counter this. How about this for a loading procedure: with slide locked back, insert magazine, pull trigger, drop slide. This breaks the connection between the trigger and the sear by moving the disconnector out of the way. Or how about this: Slide locked back, insert magazine, put a thumb on the hammer to keep it from dropping, drop slide. Both are terrible practices and dangerous habits….. and I have seen ND’s resulting from technique #1.
One thing you can’t see in the pic is the different GC sear, with the “sear depressor” and spring. I never really studied this out as I have not worked on many GC’s over the years; I started avoiding them early on when one fired as I chambered a round. The sear depressor is supposed to mitigate that.
The following is by no means GC specific but this one was a good example. The slide-top radius was way off center, leading to the slide’s side flats being of very different heights. Doesn’t hurt a thing and one would hardly notice it in most situations. But…. when you cut a dovetail in, it really shows. Left side:
Those slide serrations BTW, before I chamfered the bottom of the slide and deburred each individual cut, were so sharp at the bottom that I was able to saw a pencil in half in about 20 seconds.
Right side, You can see that the break line from flat to round is almost an eighth of an inch different. Like I said no real harm but not acceptable in a gun that will be called “custom”:
And here it is from the front. The line drawn is at the level of the lower break line:
The fix. I have cutters I’ve made over the years for just this kind of thing. This one played well with the GC’s top rib which anyway, was about .020-plus off center. Now it’s centered and ready for further work.
Now from the front, the break lines are at the same level, the rib is centered, and there’s a nice border which relieves me from having to deal with that break line being wavy due to the side flats not being very straight and parallel:
Many 1911’s suffer from this, not a boon to good function at all. Where the barrel has been stamped “Colt .45 Auto NM”, the displaced, bumped-up metal makes draggy contact with the underside of the slide’s locking lugs. Super-easy to make this go away, I mean literally fifteen seconds of workmanship at the factory could have made it a non-issue. Barrel fit on this gun was far from what anyone would consider “NM”; slide to frame was nothing special. You guys that know Bullseye and GC’s historically, I’m curious if they were ever really better for target shooting? I think maybe they were at a time when 1911 smiths were fewer and high-end custom Gov't Models were less numerous. But I think it’s safe to say that any decent custom 1911 with a Kart or Wilson or other primo barrel properly fitted and with a 4lb trigger would out-shoot this or any GC from the last, I dunno, 2-3 decades….?
And finally, for now—as with slide-to-frame fit, I don’t think barrel-to-bushing fit has to be the ultimate to deliver OK accuracy but it also “don’t hurt none” and is of course considered kinda necessary on some custom guns. One might expect a GC to have both to the degree feasible in a factory gun, but not really. In this pic you can see the bushing tipped sideways on the barrel, indicating that its fit to same is really one of pretty generous clearance in all directions. I like to fit them so the barrel can move up and down the requisite amount (about 1 degree), and have very little side “wiggle”. Not the most critical thing, I will grant ya. But easy enough to do if you want the most accuracy attainable.
Also in the pic, I really like hammer struts that are turned to a diameter at the bottom.… most are not anymore, so I have a little fixture where I make it round like I believe JMB intended. As you can see, I think it may have been intended as a reassembly aid. It makes a very handy slave pin to pre-align the sear and disconnector before inserting the sear pin from the other side. Also in the pic, the trigger that is replacing the original heavy and rattle-loose Colt bit: an EGW. I have narrowed it to Gov’t width, I’ll get a pic of that. when I can. In 2002 I proposed this design to Greider and EGW, where there is not an overtravel adjustment screw, just a bump of trigger shoe material that gets trimmed to allow proper overtravel. I'm not a fan of screws on guns and I'm glad George ran with the idea.
Last vestiges of the Eliason sight cuts going away. Good riddance sez me.
