Picked up an Umarex S&W M&P 40 CO2 pistol. It's awesome, except after about 5 cartridges it now immediately dumps out all my CO2 after screwing it in. I've done a little research, some say to tighten the ring around the puncture pin. Others says to take the magazine apart and put gasket maker where the seal is. Anyone do a break down and repair of your CO2 pistol mag? What did you do? Once again any help is appreciated guys, I'm fairly new to the air gunner world in general. Already having problems with CO2 guns, maybe I should stick with break barrel or PCP
I don't know if this helps, but all of the CO2 dumps out of the top little hole that sits behind the bb loading area, as well as shoots out the bottom of the magazine. Most of it actually shoots out of the bottom.
