MontanaMan,
One fallacy in your post: a guide rod hole in a bushing makes it non-standard. A standard bushing in fully enclosed.
Other than that we're good-to-go.
MontanaMan is right. You and Magnumdood are confusing a barrel bushing with a spring plug. The barrel bushing has nothing to do with whether you use a short or full length guide rod.
If you're going to try to argue about this stuff, at least use the right names so people know what you're trying to say.
