||Works as expected.
I have a full metal WE M9 and a HFC M9. This magazine works like a charm on both gun.
Can finish all the rounds in the mag under regular firing rate.
Holds 26 rounds.
Fits guns perfectly
Not deep charging valve like some of the 1911 models.
Don't work very good when temperature is under 50 degrees....but then this applies to all gas gun mags.
