I swapped a black saber with the gray ffg, basically just swapped the frn scales. Just swap the scales, don't change lockbars or anything. Works just fine and I sold the gray one for what I bought it for.
That's the way to go. If you start swapping metal parts, then your lockup is going to be slightly different... If you just change the plastic and keep all the metal together, then it'll be the same as before.
Someone I bought a Delica off of didn't do that, and the lockup was a bit weird, but it has broken in. That and the wrinkled/bent washers :thumbdn:
