I have been looking at getting a new bushing for my Citadel but cant figure out which would be correct one for it, obviously not the commander size I know that but I found a stainless one I want but there are three different sizes, there's standard, that's all it says , there's special 702 x 570 and gov match. any one know or would be able to tell me which mine takes? its a Citadel CIT45FSP full size

Measure your slide ID and barrel OD with a caliper and order an angle bored bushing from EGW. This is the best way to proceed.

Barrel Bushings at EGW

You will have the best possible fit this way.

Standard bushing are normally .699 x .580 and normally fit a little loose from experience.

Special Bushing .702 x .570 will need to be lightly hand fit,made just slightly over sized.

A match bushing will be way oversized and will need more fitting than the special bushing.Reamers/Drill attachement/or lathe needed for this one.
And patience if youve never installed a Match bushing.

Like other poster said,best bet is measure your slide ID (larger number) and your barrel OD (smaller number) and order from EGW.
I always order one thousanth oversize and do a final hand lap.
And yes,Angle bore is the preference so you dont get springing in your barrel.

ok so there is no set number for it? I can get ahold of a micrometer I was just hoping I wouldn't have too, oh well and id prefer something in the middle, a little better than factory but not requiring gunsmithing or pro fitting as every time I want to take down the gun I need a wrench and tools. Thank you for the input guys but angled bore is better is one main thing I'm taking away from this I had no idea

Correct, there isn't a set number. You need to measure your barrel and slide and buy the corresponding bushing from EGW. A micrometer won't help you with the slide ID unless it is an inside mic. Get a reasonable caliper and measure both with it.
