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


Always Enjoy Free Shipping On Orders Of $200

Product Description

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.*

*Will not work with 10mm ammo.*

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. Good product; colors aren’t accurate

    Posted by Unknown on Aug 25th 2019

    Good product, fit my need for adding extra rounds and extra weight to the mag for quick reloads. I ordered the OD green and it is more of a forest green, not the look I was going for. Buddy of mine ordered the coyote/bronze and they are more bronze than coyote. For $40 a pop, colors should be true and they are not.

  2. Highest quality mag ext there is

    Posted by Nick on Jul 12th 2019

    I’ve used TTI mag exts for my 43 and the extensions for the 21 are the same highest quality product you expect. This ext truly does give you +4. Do not waste the $5-$10 on the cheap plastic mag exts, do yourself a favor and splurge for TTI extensions.

  3. easy to install and its a great addition to the magazine

    Posted by Unknown on Apr 15th 2019

    Installing the base pad kit was a breeze. I especially like the fact that it looks great and adds a few additional rounds to the mag.

  4. Buy this one...

    Posted by Brian on Mar 18th 2019

    I bought four different mag bases to test before committing to one for competition. Tartans had the best machining and finish hands down. The install and removal for cleaning is the easiest, and most secure. No rattling or off center machining. Works flawlessly and came with a spring. All my mags are getting these.

  5. great magazine base plate

    Posted by 1999bankai on Feb 18th 2019

    works great, those few extra rd’s makes a lot of difference! the quality is unmatched!!

  6. Great

    Posted by MH on Dec 7th 2018

    If you need extra rounds you cannot get wrong with this + 4 pad, Very well made and easy to install once you get the extra lb spring compressed. Wished I had bought more.

  7. Base pad kit for glock 21 and 41, 45acp.

    Posted by Ricky L. Lamona on Nov 14th 2018

    The best mag. extension out there. I still have more to buy U need these mag. extensions for : IDPA , USPSA , STEEL CHALLENGE , etc. I give them a 10 out of 10 .

  8. Good product if tuned!

    Posted by on Jul 19th 2018

    I have no major problems with this product! Having said that there are issues if you don’t know how to install them properly. I initially use these as a drop on part without thinking about how they needed to be installed. My magazine jammed between seven and eight rounds which would have been a problem in the field. Once I cleaned out the base of my magazine and beveled the edges the magazines fed fine otherwise the extra power springs will hang up on the edge of the magazine base. I love Taran tactical products that some people really need instruction to use them correctly.

  9. Best +4 Ever!

    Posted by EH on Jul 14th 2018

    Perfect!, installs in seconds, flawless craftsmanship, zero failure rate in my useage, use for everyday duty carry. 1000% reliable and god forbid, a critical life saving device to keep me in the fight, and put rounds on target if the time comes to do so. I have ran out once early in my career and after that, I carry over 100 rounds now, and the TTI base pad brings me near 200. When it hits the fan with multiple threats, the more rounds the better off.

  10. Great product

    Posted by Jonathan on May 22nd 2018

    Easy install. Fits the mags perfect. Mag functions flawlessy with +4 round capacity. Great for my bowling pin gun.
