Switch to an aftermarket piston head setup to eliminate the chance of it happening again. Once it happens, it will happen more and more frequently until you swap the part out.

I have some cheaper ones ($8) that use a high quality German o-ring in stock if you don't want to spring for a fancy schmancy one. Can ship anywhere in Canada for $10 via lettermail.
I'm still new to airsoft. I'll read up a bit about piston heads in the upgrade section and see what I should do. Fancy or plain....not sure yet.
