Hey folks, I would appreciate a little patient guidance from any who might be willing. I measured the dimensions of my slide where it is bored to accommodate the barrel bushing. It seems that the minimum dimension (measured from side to side) is about 0.7040 inches; the maximum is about 0.7115 inches (measured as close to top to bottom as the geometry allows). Transition from minimum to maximum seems to be relatively gradual.
This seems to me to represent an alarming amount of egging in a bored hole. Kuhnhausen’s drawing says 0.699 plus or minus three thou., Obviously I am well over that, but am unsure of the repercussions. Needles to say, I have a lot of play in the bushing, and I’m not sure that even an EGW custom replacement bushing will help much.
I probably should mention that I originally bought the gun new, the slide has never been near a vise, and that there is no sign of batter in the bushing area. Maybe this thing needs to go back to the factory?

According to the US Army blueprints it's 0.699 plus 0.003 inch - not plus or minus. But, that's nickel-dime stuff as yours is from 0.002 to 0.008 above the max.

That's what I recommend you do - send it (just the slide) back.
And you're right in saying a custom EGW bushing wouldn't be much help. They could probably even make an oval one, but it would be kind of difficult to install.
Just out of curiosity - who's the manufacturer?
Thanks for the reply niemi. It's just a cheapie Springfield GI. I expected it to rattle, but I suppose not quite like this. Looking at it philosophically, at least I can pretend that my lousy results at the range are the fault of the gun.
IMHO, If you bought it new (forgot the 1st part of thread. You didn't, eh?) I would send it back. Most mfgrs don't warranty past orig buyer. If you have no close (free) gunsmiths as friends, I suggest checking with EGW as how you should measure (requires $29.95 caliper) the bbl and slide. Then order a bushing to fit. IF you want to spend more Federal Coupons, you could order it angle-bored.
LAST CASE _ send it to EGW and, Im sure, they will make it RIGHT. You will have NO problem selling a gun by him if you don't like it.
From what I have heard Springfield extends their warranty to anyone that owns one of their guns, new purchase or not. I am the original owner, so no problem anyway. Actually, berkbw, that kind of touches on the underlying reason for my starting the thread. The Springfield folks are so good about their warranty policy that I feel concerned about unintentionally abusing it. If I could throw $50 or $100 dollars at it to fix it without sending it back, I would gladly do so.
But if it would involve slide welding or replacement, I suppose that probably should be on them. I just can't think of any relatively low dollar fixes, so I thought that I would poll you troops to see if one existed.
The only way I can think of to make the bushing fit into the slide properly is to bore/grind the front of the slide so it's round - and also oversized. Then get an EGW custom bushing.
That's a lot of work and moolah to correct something that should not have made it out the factory door (except in some employee's lunch pail!).
My 60+ year old Remington Rand slide is only 0.003 inch above the max spec. Yours is about three times that because it got made that way!
I certainly wouldn't feel sorry for SA, but I would make sure (real sure) my measurements were properly taken with a good-quality instrument.
I would think all you would need to do is HAND (that is do some hand sanding/lapping) fit an oversize bushing.
So it takes a bushing wrench to get it out.
You'd be suprised how round a hole, that is only .008 oval, is.
And the eager purchaser comes to the rescue of the manufacturer?
Wonderful!
Should I be insulted that the bushing would fit better than what the next factory one does?
Or would I have a gun that shoots better yet?
My apologies for ruffling your feathers. Guess I should have taken a break from the keyboard and read it one last time before poking the Submit Reply button.
But Glick's gun is a GI model & not made to the GI spec in this one fairly important area. I don't really care if Glick fixes it himself. But if it was mine, the slide would be on its way back to the people who made it wrong in the first place.
Here's another way of thinking about Glick's gun.
At a distance of 50 yards (I'm a Bullseye shooter) with a mid-spec USGI (not National Match) bushing, the vertical slop between just the bushing and slide could theoretically contribute to vertical group dispersion/stringing by about:
* 3.3 inches in a mid-spec USGI slide, and
* 8.3 inches in Glick's slide.
These figures are based on data in the blueprints and the data from Glick.
And if you figure in a shooter's personal wobble area those numbers really open up!
Clark makes a special bushing that is oversize and uses 3 lugs. This may work very well in your case
