If you are going to use a G34 you are pretty much limited to using 9x21. As to what bullet weight to use, that is going to depend a lot on what kind of comp and/or barrel porting you use. As for what barrel to use, I would use a Bar Sto.

Usually, it's best to build one out of a 3 pin receiver since the loads necessary to make Major are pretty hot and the locking block can use the extra support.

Most use lighter bullets (115g) when using a comp'ed gun. KKM, Barsto and others make threaded barrels which can have a comp attached (like T.H.E). If I recall, Matt likes to use a 17 slide (which he lightens) due to it's lighter weight.

Anyway, Matt can answer the questions himself, he has the most experience doing it than anyone I know.
