The gas distribution system is different. The TPX has a threaded regulator while the TiPX is held on by an o-ring. Also, the TiPX has a thinner cutout for the remote line on the rear of the marker and the regulator banjo comes pre-threaded with a plug for the remote.
The internals are essentially the same except a different angle in the breech of the TiPX to help with positive paint feeding.
