    A solution for a problem that never existed!
    For the price of the extensions and tools you can buy a dozen of mags! Train and train your reloads and you will be fine!

    • You really just need a Glock punch and a small C clamp. At least that is what I use whenever I strap down my Glocks mags.

      But they are a solution for people shooting USPSA limited, that is what they are meant for.

        ETS and Magpul have comp legal mags now

        • I have 140s from both companies.

          I like the Magpuls, they are easy to take apart, and are reliable. But they only hold 20 rounds reloadable. Because they are easy to take apart, they are easy to clean thus they are the mags I prefer for short stages, or for my every day practice.

          I dislike the ETS mags, they are difficult to take apart, they are unreliable, and the only hold 20 rounds reloadable. These mags have never left the house after my first couple of range trips, they are junk not worth a dime.

          But a Glock 17 magazines with a TTI extension are superior for one simple reason, they hold 23 rounds reloadable. But they are difficult to take apart so I only use them for the stages that require that many rounds.

          But being that I shoot PCC I have the option for the Glock 33 round magazine, and the ultimate a 33 round magazine with the +2 base replaced with a Taylor Freelance +10 extension, which gives me 41 rounds.

    That didn’t feel like a Brownell’s commercial at all. Here I was feeling duped into watching a Brownell’s commercial instead of the wonderful original content that it was.

    • Jon in CO

      I never would’ve known it was a Brownells ad until the end. Thankfully they told me that they sponsored the content.

  • PK

    No Brownells discount code? I feel like there should have been a coupon.

    • Gary Kirk

      For the overly redundant advertising Brownell’s is getting on this site, you’d figure they’d give us one just for having to look at their logo so often..

  • Reef Blastbody

    I like the theory behind the +2/+whatever basepads for various magazines, but for f**k sake, $40+ a pop? I’ll stick with Joe’s solution; spare magazines.

    Greg Cote carries a +2 basepad that fits a large number of Mec-Gar OEM magazines, notably the CZ-75 and CZ P-09/P-07/P-10C, and possibly Beretta 92 magazines, and they’re much more reasonably priced at around $5 a pop, though still expensive for what they are; an injection molded block of polymer with a stamped sheet metal clip to stabilize the magazine spring.

    • Those are meant for people shooting USPSA limited. $40 + 25 for the magazine is a lot cheaper than the $130 my STI 140s cost.

  • Don Ward

    It’s a clip!

    No wait. These are actually magazines.

    *Dabs sweat from brow*

    Carry on without me.

        A Mag lip is actually a thing though..

    • USMC03Vet

      These are not magazines. I can’t read summer’s hottest fashion or who is dating who.

  • Edeco

    Starrett punch, classy! Mag tool to hold the mag? You must be joking and that’s for something else.

    Anyway one thing I’ve learnt is to wear eye pro. One might plan to aim the spring away from one’s retina, and catch it with a thumb. But yanno, if it takes some fighting to get the plate to slide without cutting a thumb on the metal lip, and a squirrel hops on the window sill I can get distracted.

      Glock mags have tabs on the sides to lock the base plate on. The mag tool is basically a one trick pony set of pliers to compress the side walls so the base plate will slide off. It can be done without them but they make the process a lot easier.

      • A small C clamp will also do the job. I have one on my workbench for that reason.

        • Nashvone

          I’m sure there are several ways to get the job done. In this case, someone figured out another way to separate Glock fanboys from their money.

  • BattleshipGrey

    OR, you could get two 27 round Magpul mags for $4 less than one of those fancy extenders and still support Brownells.

    • Those wouldn’t be legal, those extensions are for the 141.25mm magazine size limit used for limited. The equivalent Magpul magazine is the Pmag Glock 21, which in reality are only 20 rounds reloadable, which leaves you 3 rounds short compared to using the TTI extensions.

      • BattleshipGrey

        I have an idea of what you mean by “reloadable” but I’m not sure how to phrase it. So, you can have up to 23 rounds in each reload, to put it another way?

        • For me reloadable is being able to go a slide forward reload without an undue amount of force.

          For example my MBX 171.25 magazines for my STI will fit 30 rounds, but if I want to do a slide forward reload I can only put 28-29 rounds.

          • BattleshipGrey

            Ahh, gotcha. I’ve known of the concept for a while, just never heard it put that way.

  • Russ

    Damn Facebook, video keeps stopping after a few seconds saying it can’t be played. 🙁

  • Broz

    The ‘Modification minute’ is a great idea…thanx

  • Twilight sparkle

    I’m less interested in the brownells commercial than I am in the taran tactical base pad. I would like to see a side by side with hyve products

    These extensions work, but have a tendency to explode when they hit the concrete. The set screw holding the pin in the rear is TOO SMALL to actually get any torque. I end up using a dab of super glue on the pin to keep it in place. To add to that if you run a magwell, the pin will move out of position when it hits the bottom of the well. This is what usually leads to mag guts and bullets all over the ground . This is an issue I see at almost every match. I run these in both 9 and 40. Henning Tactical seems to have come up with a better solution with a threaded pin in the rear that deletes the explodey mag issue. On their base plates. https://uploads.disquscdn.com/images/b262708c0b2dcbea5d7b85e16116ce841fb20c4eedd0477f8f6366e810781e51.jpg
