I have a crosman model 380, .22 cal pellgun that leaks when the co2 is inserted and punctured. I cant see any seal or O-ring at the puncture point. What is missing and how can I fix the problem. Matt


I have the same problem and have dealt with guns for 40 years !
I am glad to see that the other folks have some realistic and innovative ideas of how to remedy this problem.
I went to Lowe\'s on a "tip" and found some very small \'O\' Rings for $ 0.87 for two and I am experimenting with them. The first try I couldn\'t crank the screw down far enough to even puncture the CO2 Cartidge. Using a larger screwdriver I finally managed to puncture the cartidge, unfortunately it still leaked but waas a much smaller leak.

Still experimenting.

I am going on-line to locate the Model 380 Schematic diagram which is where I ran int this site.

Good luck all !

When i take the first shot whith my crosman 357 revolver it is full power. the second shot is about half power, and the third shot rolls out of the barrel. this does not happen though if I wait 10- 15...


try switching the CO2 cylinder if that doesnt clear up the problem then its probably a blockage of some type within the tubing from the air supply.

I had my Crosman 357 for about 15 years or so. I never used it at all until a couple weeks ago and it worked great for a few days and I liked it so much I bought more "clips", ammo and CO2 for it and then...


Well I recently bought a crosman like a month ago, I worked great, I also use CO2, then i started using it again, and all of a sudden all of the CO2 started seeping out of the barrel and CO2 area, cartridge after cartridge, so i said screw it and took it apart, and found the area that deals with the CO2 and tightened everything up. I couldn't put it back together, so i looked for the schematics and finally got it back together, then i tested it out and it works fine now. Good luck.

Info on repair crosman 150 air pistol


This is better known as a Crossman Air Pistol and it is powered by co2 cartridges that will not last too long once puntured/installed in the pistol, they tend to leak out within less then a day if not being used so try to use the cartridge once you have it in place.
Some fire BB's and some fire pellets.
Wear protective eye wear and clothing and always fire down range never point any pistol at anyone when handling it keep your fingers off the trigger and point up or down range.
Happy Target Practicing!!

After inserting and compressing the CO2 cartridge, the CO2 leaks


You need to check the rubber o-ring seals both in the plug and there could be another up in the gun where the cartridge end meets the inside. If you have a broken o-ring you should be able to find one that fits at your local hardware store or store that sells air rifles. Hope this helps.

What part are you having trouble with?
I have had mine apart several times trying to repair a leaky valve.
Could possibly make a you tube clip.
