Got two of these as extras for my TM Glock 17, everything is exactly the same as the original that came with the pistol. Holds enough gas for 2 mags worth of shots, all the right trademarks are there and it has a good weight to it. I use ZeroOne's own Pro Gas with these and they all run great, no issues whatsoever, and they're easy to strip down for any cleaning/maintenance. Very high quality, exactly what I'd expect from TM. Also a great next-day delivery service from ZeroOne.

Got this spare mag for my TM Glock 17. Same as the one that came with the gun. Perfect in every way. Use only 144a Predator Gas and it is good even when shooting a whole mag. It is best to top it up with gas when reloading BBs as well. Buy polished BBs. I got some .25g that are rough and get lodged since they stack in the mag. They get dislodged just by firing the gun but you shoot blanks. So with polished BBs it works perfect and never had problems.
