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. Great Job TTI

    Posted by S Baker on Dec 25th 2020

    Awesome base pads, keep up the good job TTI

  2. 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!

  3. 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.

  4. Great product!

    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!

  5. 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!!!!

  6. Hit and miss

    Posted by Irvin Toglena on Aug 3rd 2020

    The machining and detail in the product is wonderful, it definitely looks great. I have them on all my G34 mags, all work perfect. However the .45acp ones, (I have 3), one of them will not feed probably, as the follower gets stuck in the magazine body. I believe the stronger spring that is included has been bent. I have since stopped using the 1 magazine due to this. Otherwise this review would have been easily 5 stars.

  7. The product is pretty nice!

    Posted by Charles on Jun 30th 2020

    I struggled to change it out with my factory base plate but once I got it it looks good. I didn’t use the spring it came with because it wouldn’t hold 17 with it but when I used my stock spring it worked just fine. I also wish there was some G21 mag well varieties that are compatible with this extension. Haven’t really found any other brands that don’t require shaving the back pin of the base plate down. It’s a small gap between the top of the base plate and the base Of the mag well that drives my OCD a little nuts because I want it flush but other than that it gets the job done.

  8. Works great

    Posted by Unknown on May 24th 2020

    Essential for ur glock 21/41 looks cool more ammo

  9. The only extension I can get to work with a Glock 21 in a MCK kit

    Posted by M Baer on May 18th 2020

    I have tried numerous magazines (other than the Glock 21 13 round stock) with no success with a Glock 21 in a MCK kit. The Taran Tactical 4 round extension does so thank you.

  10. Excellent, but could use instructions

    Posted by Richard Cleveland on May 18th 2020

    So the only concern preventing this from a full 5stars is installation. I know it might seem like user-error, but it would help if TT included a brief paper inside packaging on installation or a video on their YouTube channel. I've done other baseplate replacements and thought I was prepared, but I didn't think about how the alloy will chew into the plastic of the OEM mags. Definitely want to take caution with the install so that you don't inadvertently chew off the rails along the bottom of the mag.
    Again though - that's my only concern. Spring is very tight and will take some breaking in (it's all I can do to get in the standard 13rds).
