What exactly is a drop in barrel?
I am guessing that "drop in" refers to a barrel whose specs are loose to the point that they'll fit.
I am interested in getting a Lone Wolf 17L slide & barrel. I also really like the CCF frame. CCF recomends having any barrel (except Glock OEM and their own), "fitted" by a gunsmith. http://www.ccfraceframes.com/faq.php From the CCF website FAQ: Quote:
Is a gunsmith going to be able to do anything except alert me to a problem and tell me they don't fit? |

You are correct in assuming that dimensional tolerances for a drop-in barrel is made to fit any gun, albeit somewhat loose. If you want to see what a drop-in looks like, just look at your factory barrel. Loose lock-up, loose barrel-frame fit, etc. I agree that it you want a top-notch job, get a barrel that has to be fitted.

"lose fit" is one possibility, but the term is also used to differentiate from short-chambered barrels. Those barrels will always need to be fitted by a gunsmith.

What will a gunsmith do - take metal off the places in the barrel (lug, I'm assuming) ?

A properly fitted barrel involves threading so there is a snug ,rigid fit .For something like a M98 Mauser the barrel is cut so that the end of the barrel and the shoulder both are snug to the receiver .More rigid - more accurate !
Chambering is done so headspace is correct .Often headspace is minimum for better accuracy .Throating , both length and diameter can be critical for accuracy.Then you can glass bed the action ! In any case you start with a barrel blank , nothing precut. That's all for the best way !!

Usually, in a handgun, the drop-in barrel is one that can be installed by the owner without fitting. It will not be as accurate as a fitted barrel except by pure good luck.

Since he is talking about a GLock, there is no glass bedding, chambering, throating, or threading involved.
The gunsmith will ensure the barrel-slide fit is optimal, will make sure the barrel locking lug fits into the slide properly, and will make sure the slide comes far enough forward at lockup to reconnect the disconnector to allow for the next shot.
