hfc m9 gas blowback!

hey i got a question here. umm i was shooting at my fields with my m9 as a secondary. the i was getting ready for the next game, i put the green gas in and it exploded on me. it shot green gas out of the bottom of the mag. now every time i shoot it shoots like 2 bb's and then runs out of green gas. do i need a new mag? new gun? new gas? please answer.

It sounds like something on the intake on the mag broke.....have you tried just loading the mag with gas and then emptying it buy hand to see if its holding the gas?

uuh no. lol but i will try. if it does not hold the gas should i just buy a new mag?

If it doesnt hold the gas then you should get a new mag......maybe 2

IT sounds like the loading valve in the mag is broken. Should be an easy fix, if you have replacement valves. I've had to do it a few times with my 21 round WELL G55 mag.

ok so i put gas in and i released it... the gas came out but it did not seem to be very much. which basically means (in my guess) that is rejecting the right amount of gas it needs or the valve is broken. but thank you guys for being helpful. i will buy new mags!
