Beretta's have a beefed-up slide for their .40s, as does Kel-Tec, even though they dropped their .40.

Browning HPs I believe also have a heavier frame for their .40s.

The older EAA Witnesses did just require an upper-half change to go from 9mm to .40. The newer ones have a bigger frame and require just an upper-half change to go from 9mm to .40 to .357Sig to .45 to 10mm etc.

Also, the Sig 239 uses different frames and slides for 40/357 and 9mm so are not interchangable.
