+4 Base Pad For Glock 21/41 .45 Cal OEM Magazines


Always Enjoy Free Shipping On Orders Of $200

Product Description

*Will not work with 10mm ammo. Our extensions are designed to work specifically with their intended magazine, the slightest off-angle may cause failure to feed or other malfunctions.*

GLOCK .45 +4

*Not for sale to California residents. A courtesy email will be sent to CA residents who place an order for product that has the capability of taking a magazine past ten rounds. Ultimately a refund will be issued. CA residents can only buy +0 base pads or GLOCK 43 and GLOCK 42 base pads. The 43 and 42 base pads do not take the mag capacity past ten rounds.

The pin set screws are set with Loctite® at the specific tension we recommend, and will generally never need an adjustment. Tightening the base pad screw is not recommended and may be difficult because the screw is set with Loctite®; trying to force the set screw to turn could result in stripping the screw. We do not warranty base pads for stripped heads on set screws or pins lost in result of tampering with the set screw.

*Remove the metal insert at the bottom before installation*

*Will not function with early generation Glock mags that have u-notch cut feed lips.*

This Taran Tactical Innovations GLOCK base pad works on GLOCK models 21/41. This TTI base pad will add 4 extra rounds of .45 ACP to the magazine. This base pad does adds a little extra weight to the magazine which helps the empty mag drop free easier for faster reloads. This TTI GLOCK base pad, just like all of our base pads, is designed to give you the edge over your adversaries. We use our patented push pin design to lock the base pad to the magazine, which makes for easy field stripping and cleaning your magazines between stages. Just push down the pin, slide the base pad on and push the pin up to lock the base pad onto the magazine. Our one piece design is great because there are no extra parts or tools needed to attach the base pad to your magazine. The base pad itself is machined out of billet aluminum and is hard anodized to ensure durable long lasting color. All machining and manufacturing is done in the USA.

  1. Follow the instructions

    Posted by Rob Mathis on May 18th 2021

    Absolutely, hands down worth every cent. Just read the instructions. Install new spring and base pad and load half way and let sit over night then load the rest. Would definitely buy again.

  2. Always the Best!

    Posted by Jim on Mar 22nd 2021

    These have a great fit and look awesome adding additional capacity. Using them in USPSA they are being dropped all the time and as tough as they are looking good.

  3. Clever idea

    Posted by Ryan on Feb 27th 2021

    -Works with Suarez magwell to make a seamless fit and finish.
    -No more waiting for the mag to eject.
    - new mag springs are cheap maintenance on all mags.
    -extra weight is compensated by using lighter ammo( liberty munitions) but otherwise utilized to mitigate a bit of recoil.
    -The extension (w/ or w/o griptape) also allows for an extra grip on the mag for better reload.
    - gets them out of the belt much quicker.

  4. Simply the best.

    Posted by Nick on Feb 18th 2021

    If you're wanting to run anything but the stock base pads, this is the only solution. Even if you aren't looking for more capacity, the spring, positive drop, and balance in the hand are nice upgrades in themselves. Smaller pads for CCW are great for that extra finger on the gun, and for those of us in the 45acp world I wish this worked with 9 round Glock 30/30s mags, but unfortunately they do not. Instead I run a Pearce pad on the 9 round for max concealment and grip, then one of these on a full size mag for the reload in case things get spicy.

  5. Work of art that works.

    Posted by Wishooter on Feb 5th 2021

    These are beautiful and work flawlessly- in my 10 mm Glock even though Tarun does not warranty that they will feed properly for 10mm. As it’s really hard to find a decent extended basepad for 10mm to work with a magwell these are a lifesaver. Only downside is cost, but I grabbed the titanium blue which look great and are marked down.

  6. Great Job TTI

    Posted by S Baker on Dec 25th 2020

    Awesome base pads, keep up the good job TTI

  7. Quality build + Balanced

    Posted by Todd E on Nov 26th 2020

    These Glock magazine basepads are a higher quality build and balance than ANY of the competitors; the balance of the pistol in hand is maintained, it's not oversized or cumbersome feeling. Great job to the R&D teams, I look forward to more products for Glocks from TTI!

  8. Look and Feel Great

    Posted by Unknown on Oct 27th 2020

    These base plates exude quality and I’m glad Taran is still supporting the .45 glock platforms. Will definitely be buying more of the OD greens.

  9. Great product!

    Posted by Jason S. on Oct 12th 2020

    Unfortunately, due to the ammo shortage, i wasn't able to put to many rounds through the mags I've installed these on. That being said, the times i have gotten to shoot, they've been flawless in my Glock 21 Gen 4. They look and feel great!. I kinda wish they were a little cheaper, but who doesn't? I would definitely recommend these mag extensions and i will buy more for my other guns. Thanks TTI for such a great product! 17+1 in a Glock 21 puts it on par with the stock Glock 19 and 17, but with America's round! Outstanding!

  10. Highest possible quality on every small detail including design

    Posted by Glockdog7 on Oct 6th 2020

    I have never found a more efficient and well performing add on part for a Glock. I picked up a Glock 41 for home boogeyman protection. 17 rds of Lehigh xtreme defender will render the meanest boogeyman fangless pretty quick. Just what I was looking for not to mention the aesthetically pleasing appearance of the anodized part. Wish you guys made an aluminum colored anodized unit or silver to go with my threaded Kkm barrel. Bad ass parts boys!!!!
