Hi Scott there is no difference between the 2 actually

Scott, CZ only gives some basic differences : [Back by popular demand is the SP-01 Phantom. Essentially a polymer-framed SP-01 Tactical, the current Phantom received the benefit of years of development in new polymers, sharing the same fiber-reinforced formula used in the P-09 and P-07 with Decocking Lever, Firing Pin Block Safety. With interchangeable backstraps and mag compatibility with the standard 75 platform, the SP-01 Phantom has long been a favorite in the CZ community].
