Don't do that... Like Coach said, only the XM series are meant to be used with CO2...
And besides, if the idea of using compressed air (read here 2000 psi)... just don't... we tried it and... obviously what had to happen happened: first we were unable to fire the grenade using a launcher, since the pressure was so high we couldn't use the launcher trigger.... we used a punch and a hammer instead... and when it wend off... wwoooooaaaah... get out of the way (it was the rubber head grenade by madbull...) just don't try it
.... oh and BTW, we completely internaly destroyed the grenade with this precedure...
