AW custom G17 help

[Dan1234]

Hi I have had my G17 for about 6-8 months now and the last week or so I have noticed when I take the chrome magazine out of the pistol it is very cold and I am getting less shot count and lower range out of my BB could anyone help with this?

thanks Dan

What have you changed?

Anything and everything is relevant.

Mags always get cold, that’s the physics of  liquid in the mags expanding into a gaseous state

I only changed the bb brand but I seem to have fixed it as I stripped the pistol down I saw a bb was stuck in the mag release mechanism
