Mag Leak? How to Check

[yosemitesam]

Hi

ive just brought a S/H C02 pistol (Witness 1911 by KWC) and fired 2 mags through it. Is this normally all a cartridge lasts because I left it and it was still blowing back when empty but when I came back to it later it seems empty. It doesn’t hiss so I how do you check if it’s a leak or just out of gas?

thanks!

Put a fresh bulb in, dunk it in a bucket of water and wait for the bubbles. or put your ear to the mag and listen you'll soon find out if you have a leak.

Spray soapy water onto the seals and look for bubbles
