Thanks for the advice. I will charge the one I have and see how it is, if no joy Ill get onto ebay.
Another question i have is, the m9 is a gbb, it only really works with green gas which I've never been able to get. However I have found a mag that will take a co2 bulb. I have plenty of these already as I also have a co2 Walther ppk not for use airsoft ing obviously. If I convert the m9 to co2 will it still be allowed to be used or will it become too powerful?
