IIRC, one of the services offered by the CZ Custom shop is throating the chamber for reliable 147 grain feed. I could be wrong, but thought I had seen a gun from CZ Custom that had that done to it.

My SP01 does not like 147s. It runs just fine with 115 and 124, in all of its magazines.

My P01 has no trouble with them, except with some of the SP01 magazines. The other SP01 magazines will feed 147s in the P01.
