Bbl. bushing for a Norinco

[venison]

As the factory barrel bushing in my Norinco 1911A1 blued clone is not quite round I'd like to replace it. I thought of EGW since they make great products.

I do not have the means to properly measure the diameter of the slide so I'd appreciate if somebody could let me know what it is.

Eventually, what the different gaps must measure for a reliable (non match) 1911?

Really can't have someone measure their Norinco cause it may not be the same as yours. However I suspect that an Ed Brown drop in bushing would work just fine on there.

Every milspec type 1911 I've ever tried it on it's fit well.
