Most Helpful Positive Review matches the lines/look of Kiger 9c Pro
Design flows perfectly with the lines of the 9c Pro with sct19 magwell addition.
Most Helpful Negative Review Save Some Money
First off, this thing looks cool and appears to be of good quality. However, this mag extension is very bulky and provides very little benefit. I prefer the Tyrant Designs mag extension, it seems to be easier to manipulate.

adds few rounds to ur mag

by vik, Verified Owner from OR, United States Written on December 26, 2025
Good quality mag extention , i wouldnt say its better than other brands for 1/2 the price , also does make ur glock much heavier , even when mag is empty , but helps with reloading , mag just flys off.

Look Cool But Thats It...

by Austin F., Verified Owner from TX, United States Written on June 6, 2022
These mad extensions look awesome but are horrible to install. Both springs that came with this product did not install correctly into the feeder. I was able to bend one enough to make it work but the other one i got is no good and ended up in the trash. Ill be looking for other brands my next time around.
Pros:
  • Looks
Cons:
  • Install a pain
  • Not right fit
Would recommend: No

Absolutely worth every dime

by kurisu, Verified Owner from PA, United States Written on October 20, 2020
Love this mag well extension. This is very good quality and makes reloading very easy. I would highly recommend this to anyone who wants a solid magazine extension. The way it attaches is also very solid had no issues with mag drops on concrete.
