Nope, TM P226 has a different loading nozzle design, partly reflecting the fact that the TM P226's nozzle retraction spring is side-mounted.
Piston lid is similarly dimensioned, though I wouldn't put a stock TM suction-cup lid in anything. They're more fragile than the WE ring-plate lid design and mounted only by friction. Bad ideas all around.
As for the hopup, the sleeve's the same, so's apparently the dial and depressing arm, but the chamber itself is very different.
