I was wondering what tolerance would be acceptable in the barrel/bushing area on a carry 1911 full-size. My barrel measures .576" at the muzzle, and the bushing's i.d is IIRC .581. Also, the bushing is canted in the slide and has a sloppy fit. The slide's I.D. is .700", and the locking groove is in pristine condition, so I won't have problems fitting a bushing, however, I don't have the confidence to increase the i.d. of a bushing or decrease the o.d. of a barrel, so I'd rather use a drop-in bushing with a little polish. In short, how much clearance should there be between the barrel and bushing? I'm not shooting matches, so I was thinking .002"-.003" would be about right. Thanks in advance for any replies.
