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. 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.

  2. Works great

    Essential for ur glock 21/41 looks cool more ammo

  3. 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.

  4. 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).

  5. Glock 21 Mag Base

    Posted by James West on Apr 3rd 2020

    High quality product. Fits my gen 2 Glock 21 mags. The Olive drab is off the color doesn’t match any other Olive Drab I have. This is a common problem in this industry especially when anodizing aluminum. Also, I was able to scratch the anodizing with a plastic screwdriver handle. The color needs to be significantly darker to be even close. The pin that keeps the mag from sliding off the base does not work with my aftermarket mag wells. I have two one from Zev and one from Lone Wolf. Pin hits the mag well in the back near the Mag well mounting tab that secures the mag well to the pistol. I like the weight, mags drop easily and the additional 4 rounds fit nicely. I can grind out a track for the pin so the mags seat correctly but if you have an aftermarket mag well, know if you use this product you will likely have to “modify” your mag well.

    Made in USA, purchasing higher than average quality parts like these +4 G21 basepads which support the TT shooting team as well!?!! It's a no-brainer, I buy a box of 3-6 of these every Christmas season for the G17/19, 24/35, and now the 21 mags are getting squared away. SUPPORT the SPORT, go with TT and John Wick!

  7. Basepad for Glock .45

    Excellent fit and finish. Machine work is flawless

  8. 17+1 of .45acp is Comforting

    Posted by Enrique McSkootzee on Dec 9th 2019

    Well just got my 2nd mag extension for my G21. Love these extensions. Even though im a 9mm guy I Love my G21 during all hunting seasons that i can OWB Carry. During General gun season on Public tracts in FLA. your restricted to 5rd mags in any Semi-Auto Centerfire Rifle but no other restrictions on Handguns, shotguns if Hunting non migratory Birds, and Rimfires. Now w/a .300 blackout 5 rds is Plenty on Whitetail deer blind/stands but when U come across Hogs, wheres theres Zero restrions on size, sex, or bag limit so 5rds goes Fast n thick Saw Palm so going for a .45 thats topped off w/18rds of Critical duty or Lehigh extreme Penetrators is a Phenomenal Tool on the Hip n hands. My only slight complaint would strictly cosmetic due to the OD Green is darker than the OD GREEN that i get from TTI for my PPQ Navy which is a nicer shade but that’s literally my only gripe or i guess that state of California made a bureaucratic $1 off the Sale of Gun accessories. Oh and if anyone on here from TTI is reading this how about making ur own affordable as for ur products sell Glock mag takedown tool for Sale oh and Jade is Smoking Hot

  9. Superior to all others
