"Excellent Magazine for those that want the extra mag capacity but for a more reliable Co2 delivery system. Loads, Feeds and Fires flawlessly. constructed very well also. it also supports custom mag plates some plates might need some foam or felt glued to the inside of the plate as a gap filler but that definitely not an issue. the ONLY reason it doesnt get 5 stars is the gas consumption and the strange loading design with no instructions. Typically a co2 cartridge is inserted tip first. the bottom of the cartridge gets push screwed by the bottom cap into the piercing nozzle valve and the magazine gets pressure. this is opposite. the canister gets put in butt first. the co2 tip gets pierced by the cap screw and the co2 free floats around the canister in the chamber that its loaded in.... odd but i guess its done that way to provide less pressure so it doesnt break your pistol. but that comes at the cost of efficiency. one mag dump and the cartridge is spent. but overall great buy.
