ProWin magazine, Glock 17/18, long - 52

ProWin's long Glock magazine for Tokyo Marui gas-operated (GBB) Glock 17/18 guns. Also fits other Marui compatible Glocks. May be a tight fit on guns from other manufacturers.

NOTE! The user should note that, like other airsoft equipment, magazines also require maintenance. Most leaks are caused by a dry magazine (it has not been lubricated and therefore the magazine is no longer tight). Valves may also require tightening from time to time and it is worth purchasing a valve key for maintenance. Please note that long-term storage can dry out the magazine and therefore the magazine may leak after a break in play. Lack of maintenance or user error is not covered by product defect liability!
