Are these aftermarket extended magazines OK?

    Just a short video about round counts you can play while brewing coffee or something.
    Has anyone tried their aftermarket products? I found them while looking to buy some more magazines for 357 just for the cool factor of having it stamped but they're $40/ea on official website but if I could have 20-rounder for the same price I would like to go that way as long as they work fine.

    I can only assume they make extended magazines for such unpopular gun like Steyr pistols because they're local to Steyr USA.

    I haven't tried them personally but from what I've heard they are really bad. I can't confirm but Ive heard that they are pro mags made for another gun with the mag catch cut added in so it will fit a steyr.

    Promag Browning Hi Power mags fit and lock up with no modification. Function requires cutting a small notch between the feed lips on the rear wall of the mag.

    Reliable function in the one I have required switching to a Steyr mag follower and a Wolff extra power spring for a Glock 33 round mag.
    ihatecars and Case like this.

    Don't buy them they don't WORK !!!
    Joe's pawn shop was talked about some time ago and it was NOT GOOD AT ALL..
    If you what a Extended magazine for the Steyr you can use Smith and Wesson M and P mags and modify them to work . Tnsteyr has the information on his Facebook page and Has talked about in his videos

    FWIW, I had no luck in any of my Steyrs with getting reliable fxn of any retrofitted “other” magazines.
