My 1911 had a broken barrel link and got sent back to the factory (STI) for a replacement - free of charge.

When I got it back they had 1) replaced the link, 2) polished and throated the barrel (it never had feeding problems but I appreciated this anyway) 3) chamfered and polished the disconnector rail (again I never knew there was a problem here but I'm fine with it being done), 4) polished the breach face (again no problem here but it looks pretty now), and 5) reemed the barrel.

My question is about item #5. What exactly did they do to my barrel and why would they do it? What problem was corrected here? Am I now shooting a 46acp :), .453?

Thanks.

First let me say that a broken barrel link is usually the sign of a mis-timed gun.
What's taking place to break the link is, the vertical impact surface is cut to far to the rear and the rearward movement of the barrel is being stopped by the barrel link causing it to stretch and break.

I'm not sure why they did all the other things to your gun.
As for reaming your barrel I believe they may be refering to cutting the chamber deeper.

Exactly what Bob said...

By installing a longer link, reaming the barrel and shaving the face, the lower lugs will hit the frame earlier preventing a stretched link before the barrel hits the bridge. My guess is that new longer link would contribute to a tighter lockup and better accuracy. :D

Anxious to hear a range report on the results!!

Sir;
Bob is excatly right! The "reaming" was probably what I do to all 1911 barrels so they chamber lead right - cut the throat - not headspace.
