rule re barrel "factory configuration"

[InTheBlack]

the rules only allow " Internal accuracy work to include replacement of barrel with one of _factory configuration_ "

Would this prevent me from putting a regularly rifled barrel in a Glock so I can shoot lead instead of jacketed bullets?

I'm not sure what the rule is trying to say, but I did email Tom at customer service and he says you can replace the barrel with one from KKM, Jarvis, Federal, etc., and still be legal. I specifically asked about replacing the barrel of one of the ported 'C' models with a non-ported barrel, and he says that this too is allowed. If the gun was, in all other ways, elligible for Stock Service Pistol, it would still be elligible after the barrel replacement.

I take it to mean, for example, you can't replace a bushing type barrel with a bull barrel, or things to that effect.

Erik is right.  You also can't fit an extended barrel to a gun, i.e. a six inch hunting barrel to a Glock 20.  Replacing a stock Glock barrel with an aftermarket barrel of the same length is fine.
