WE PDW mags

[rubi-tong]

Hi guys, just bought a PDW today S/H.
I'm asking you experts what the PDW mags are like in the cold on propane? I stay on semi during games so cooldown shouldn't be such an issue unless it's freezing out. I prefer the look of the PDW mag over the M4 style that also came with it. It just seems to fit better too.
I'd like to get more of these and their cheaper to buy to boot, but what are they like to use in play?
