Maxx,

I was also thinking to ask how you know the original barrel is shot out? The rule of thumb I always heard for hardball was around 25,000 rounds. For lead bullets there doesn't seem to be any limit if you don't scrub the bore with stainless brushes or shoot dirt and grit through it on a routine basis. The link lugs will get loose on the slide stop pin after awhile, if the gun was fit up originally. If the barrel is a standard barrel that wasn't fit up, then you either have to replace it or find a good TIG welder to build some metal up on the link lugs and barrel extension for you to cut and file and scrape to fit. These days that's considered old school, but it still works. A third possibility is a David Chow type spring steel pad in the slide locking lug recess to remove lockup slop, but that's old school, too, these days. The Kart EX-fit is at the opposite end for the easiest way to get a tight barrel lock up.
