cold weather effect on magazine/induce FTF
 
So, I go to the range. Shooting a couple 1911 and a XD45. 20 degrees.
I had several FTF with all guns, all mags (Wilson, McCormick, SA). Each was a round not advancing in the mags. The ammo was Tula, so I don't have to pick brass out of the snow.

My theory is the steel case, cuns heating up cooling off, condemnsing moisture cause some sort of draggin, catching of the ammo in the mags.

Any thoughts?

From an engineering standpoint, what do you think occurred? Are you saying that the rounds weren't pushed up by the follower, or were they not picked up by the bolt when going into battery? I'm just trying to understand the situation.

Do you oil your mags? More than likely it has more to do with lubrication than ammo. A lot of oils and grease turn to a sticky mess when the temp heads south of freezing, specially if you have not cleaned your mags for a while. Take the mags apart, clean them thoroughly and strip them of all lubricants (no need to oil mags anyway) and see if that cures the peoblem.

Another potential scenario is if you had the loaded mags outside, brought them into a warm moist environment and them back out to the cold before they had a change to dry out, that could be a problem too. When you come inside you should unload all your mags make sure there is no condensation on them or the ammo before you head back out again.
