Co2 magazine

[Eddie5]

Iv lost the screw from the bottom of my Colt 1911 100th anniversary co2 pistol magazine. Anyone know what type of screw this is and where I could get a replacement

You may get more help if you put a picture up, mate. Personally I haven't a clue about 1911's, but chances are it's an M4 or M5 thread so you should be able to get one with the right sort of head, or choose a head you prefer, from ebay.
