Tokyo Marui vs Co2

SuperBlu26

I'm looking at getting a Tokyo Marui SIG P226 E2 or a Co2 KJW SIG P226 E2 and can't decide which to get.
I'm leaning towards the Tokyo Marui because of performance but will it be ok in the cold weather?
There both about the same price so it's not really a factor.
Thanks!

The TM, the kjw mags suffer from chronic leaky mag syndrome ( like most kjw co2 mags). And the tm works better in the cold.

Gatling

The TM every time leave it stock and stay away form the metal slide and frame ,
Have a few tm pistols and never had an issue in our climate, my hicapa's have run in zero degree weather issue free.
In 6 years only have one mag fail ,need to replace the seals other than that they have been bullet proof
