WE Hi Capa 5.1 Series CO2 28 Round Magazine

Solid build, easy feed, fits 1911 colt we well. No misfeeds. I like the way end cap has built in notch to unscrew cap of co2 compartmentry and easy to change and remove co2.

End cap not secure enough, lost cap while in side holster. Own 2 and one seems to leak and lose co2 pressure fast maybe bad seal. Othe one seems fine. I

Fits We Colt 1911 excellent, ideas identicall to OEM part. Take end cap off bc you will loose it in combat. Just hit it once and its gone.

works perfect with my Hi-CAPA 5.1 Silver Dragon

Rugged construction. 28 round cap. plastic cover over the piercing knob. Gray color matches the Caspian Baby Hi-Capa. Co2 convenience beats shlepping a green gas bottle or worse, a propane tank what with silicon oil and adaptor . Extends the grip on 3.8 models for larger handed shooters.

change Co2 piercing knob . Instead of the tiny, finger tip cutting ridge replace it with a hex bolt like on KJW or Palco/Cybergun models or a spring loaded folding tab like TSD or Win Gun 1911's. I had to use a small pliers to get enough grip and leverage to pierce the Co2.

The price is half the cost of the 3.8 models so buy this if you are a Co2 addict (like me) Once you go Co2 you don't go back to gas and The Caspian 3.8's compatibility with this mag was the deciding factor in my purchase of this gun.

It's great to have the option of getting off the green gas hassle and back to CO2 cartridges. This mag works well with the Caspian and so far I haven't had any leaks.

Drop the price about $10 - it really is a little expensive for an airsoft mag.

If you don't mind paying the price, get one of these to use in your Caspian models. You'll be a lot happier when you havee the option of using CO2 as well as GG.
