I really could use some clarification, some of the comments say this is the 3 millimeter walls and some say it's the one 1.5mm. Which one is this?

Since you didn't specify whether you're looking at the 4 ft. blowpipe or the 5 ft. blowpipe, I can't really say what 'this' is. But I can tell you that the 4 ft. blowpipe is the heavier wall tube and the 5 ft blowpipe is the thinner wall tube.

How large of an animal will this put down?

With extremely good accuracy and skill with this blowgun, you could take down game as large as a deer, however this is something I would not attempt unless you were very very adept and it was legal. For me I wouldn’t shoot anything large than a crow or squirrel.

Is this able to shoot .40 cal darts or does cold steel make a .40 cal blowgun

I don't know if the .357 will shoot .40 cal darts, but given the measurements, I would guess and say no because of the size; I own a Cold Steel .357 and .625, as far as I know, these are the only two blowguns sizes that Cold Steel makes.

Will the two foot extension fit on this?

As long as it’s not a Pro version, yes. You can expect around a 9 fps (for 5’ blowgun) to 16 fps (for 4’ blowgun) velocity increase.
