I bought an Umarex Walther CP99 Compact
pistol used from a friend. When I brought it home, I loaded a magazine with a few BBs, cocked it, and fired. It fired as it should. When I decided to replace the CO2 cartridge with a fresh one I got from a pack at a sporting goods store, the fresh cartridge won't get pierced when I put it into the pistol grip. There is a wheel at the bottom which one needs to rotate after inserting the cartridge which pushes it up into the needle which pierces it. Even when the wheel at bottom of the pistol grip is fully turned all the way, it will not pierce the CO2 cartridge allowing no gas to escape. In fact even after fully rotating the wheel, this is still a small gap of wiggle room between the wheel and the bottom of the CO2 cartridge. What should I do? This is a fairly high quality looking and feeling CO2 pistol, which I bought to use as a trainer pistol. The pistol uses 12g CO2 cartridges. It uses .177 cal(4.5mm) BBs if that makes a difference. |

Quoted:
If the replacement co2 bottle is a little shorter than the original, put a penny under it. Actually, I stood them up side by side on a table to compare. The original cartridge, and my new one are the exact same dimensions. I have thought about using a penny. While it is probably a great idea, I prefer not using quirky fixes like that until all conventional solutions have been exhausted. |

I have thought about using a penny. While it is probably a great idea, I prefer not using quirky fixes like that until all conventional solutions have been exhausted. If you don't want to try the penny idea, in that case you are going to have to go mechanical on the gun. Start by shining a flashlight in the Co2 holder and see if the piercing point is broken. Also, look at the CO2 cover and see if there is evidence that a spacer of sorts was in there but may have fallen out. Something like a hard foam glued in spacer is what I mean. If all else fails, get out the digital camera and a variety of screwdrivers and take pictures as you decompose the gun to see what may have gone astray. I have taken a number of air pistols down and had no trouble getting them back together and working again. |

I havn't tried any other cartridges, but they appear to be identical.
Only the brand is different. I'm almost certain that the problem lies with the pistol. There is a wiggle gap between the cartridge and the elevator underneath it. I have taken a few photographs. I don't know how to upload photos. Can I email them to someone here so they can be uploaded? Or is there any specific part I should photograph? |
