  • Do Base plate Mag extensions lower reliability of Glock OEM Factory mags? Could they be carry worthy?

    Posted by Mateo on June 23, 2022 at 10:52 pm

    (Sorry if this is common knowledge)

    So we know glock OEM factory mags are the most reliable option for carry, but if you were to add a base plate extension to one, could that hinder reliability of your Glock? Are they carry worthy?…

    Also if the only issue is them possibly popping off when, then, let’s say there was a way to permanently attach them, would there be any negatives to doing so, other than not being able to take them off and change the spring).

    If permanent attachment would be a good idea, then how would one go about doing so?

    Any time you increase capacity on a mag there is a chance you can lower the reliability of the feeding of the rounds.

    The main issue you’ll run into is if you’re adding too much capacity without adding longer/stiffer springs.

    I put +0 aluminum base plates on my Glock mags just for functionality with enlarged magwells.

    Just a heads up if you didnt already know. Glock sells g26 mags with their extension on it. So, it must be reliable.

    What mag are you considering extending? If it’s 9mm, Glock makes mags that can hold 10, 15, 17, 19, 24, and 33 rounds, without add on extensions (although the 19 rounder appears to be a 17+2). You can increase capacity with an OEM-designed mag.

    Honestly dude, I would just recommend the 19rd factory ones for your spare. The aftermarket ones are dummy expensive and I don’t think would ever be as reliable.

    just replace the spring and you’re gtg. I added a few oem baseplates to my oem glock mags. no issues. (besides not locking back with original spring so that’s why I’m advising a spring swap)

    Spring tension is important for feeding. Most magazine extensions that benefit from a new spring will have that spring included as part of the package. In my estimation, best Glock mag extensions are OEM+2, Magpul, SLR, Arredondo. There’s no good reason to permanently attach the extension, most will retain their fit while firing.

    Install it and test them out.
    The extensions do come with the 19x. So, they can’t be that bad. For the 26, definitely test it out at the range.

    Not with the oem ones. I have a 5 round aluminum one off ebay that came with spring. Haven’t had any issues with it and had it a long time.
