    I'm a bit confused about all the different types of Glock mags. Metal lined, full metal lined, ambi cut, non-ambi cut, etc. I have a 3rd gen. G19 and want to make sure the mags I buy will work with the gun. Does anyone have any info on this? I'm primarily interested in the 9mm versions.

    it will be harder to find factory magazines that aren't good to go than it will be to find factory mags that are.

    the ambi cuts came out for the Gen 4 glocks because of the ability for you to reverse the magazine release, and they work fine in every other generation.

    i say this, go to your favorite gun parts place that has the best deal on glock 19 mags and buy em. you will be fine.

    Currently, there are nine generations of Glock magazines.

    If the Glock has the standard magazine release, then it can use all (1st-9th) generations of Glock magazines [Type 1-4].

    If the Glock has the ambi-magazine release, then it can only use the newer (8th-9th) generations of Glock magazines [Type 3-4].

    If the Glock has the reversable magazine release set up on the standard (left) side, then it can use all (1st-9th) generations of Glock magazines [Type 1-4].

    If the Glock has the reversable magazine release set up on the non-standard (right) side, then it can only use the newest (9th) generation of Glock magazines [Type 4].

    Even though there are technically nine generation of Glock magazines, they are typically simplified down to four types.
    Type 1 = NFML (Non Full Metal Lined)
    Type 2 = FML (Full Metal Lined)
    Type 3 = FML with ambi-magazine cut
    Type 4 = FML with ambi-magazine cut & reversable magazine cut

    1st-8th generation Glock magazines. Type 1 = 1st-3rd gen. Type 2 = 4th-7th gen. Type 3 = 8th gen.

    8th (right) and 9th (left) generation Glock magazines. Type 3 = 8th gen. Type 4 = 9th gen.

    "Metal lined" and "full metal lined" are the same. The metal inner portion is meant to stiffen the magazine body so it will not bulge when loaded, as the original, all plastic one did. This caused the magazine to bind slightly in the well and not drop free of its own weight when you released it. It is a response to demand from American shooters, who want their mags to fall free right now. European gunmakers are normally not big on this, other examples including the CZ75 - which actually has a magazine brake - and the Browning Hi-Power (produced by FN for a French military contract).

    I have seen some messed up old gen Glock mags. Some that don't hold thier full amount of rounds, some where the plastic goes up too high and hits the rounds etc.

    Never ever had a single malf with gen8 mags. Gen8's drop free as well.
