P365 Air Magazine FAQs
What type of CO2 cartridge does this magazine use?
This magazine is designed for use with standard 12g CO2 cartridges.
Why does the magazine's CO2 nut strip so easily?
The hex nut is made of a softer aluminum. To prevent stripping, ensure the allen wrench is properly seated and avoid over-tightening.
My magazine is jamming. What should I do?
Jamming can sometimes be caused by a crooked follower or using a different brand of BBs. Ensure the BBs are loaded correctly and consider trying a different brand. Keeping the magazine lubricated can also help.
Is this P365 air pistol magazine compatible with my actual SIG SAUER P365 firearm?
No, this is an airgun magazine specifically designed for the SIG AIR P365 CO2 BB air pistol. It is not compatible with a live firearm.
What is the best way to load the magazine?
To load your Sig P365 Air pistol magazine, pull down the follower spring and use the loading port to insert the BBs. A speed loader can also be used for faster loading.
Can I use pellets in this magazine?
This magazine is designed specifically for 4.5mm steel BBs and should not be used with pellets.
Where can I buy the P365 Air Magazine?
