After fitting a clark drop in barrel to my slide the lockup still seems a bit "tight" as in the slide drags against metal within the last 1/4" inch before closing.I have used prussian blue on the locking lugs to find where to gradualy remove material and it appears to make full contact evenly. of coarse I have not fired the pistol yet and I intend to have my local smith check it before I shoot it. but is this something I can fix or is it time to take it in yet? any help appreciated.
thanks

dykem your bottom lugs and check for "bump" where the slide stop is just dragging on the radius
