First I would ask what range your serial is, what thousand range?
The sigs are actually done pretty good parts wise and they are very tight fitted. The skeleton trigger IS more of a preference. I know in the 500-8000 mark they used greider solid triggers and they are outstanding. The newer ones look pretty much the same but I don't know if they are greider or not. If you you like a skeltonized trigger though then definitely go with what you like. You only live once.
My 2 have good, tight bushings in them so I would't change them. If yours lock up tight I wouldn't worry about changing bushings. Reconvic has a newer ttt and he just put a Cylinder and Slide iggnition kit in his, so he can tell you what difference it has made. I'm sure he will be along sooner or later to chime in.
