The Strike Industries G42 Magazine Extension is a low drag/no snag design which allows for fast magazine reloads every time! The SI magazine extension adds 2 extra rounds to the G42 magazine! The extended grip on the extension allows for extra surface area and gives the shooter better control and increased grip. The added ergonomics of the magazine extension leads to a higher accuracy potential

    Yup! Worth every penny...

    NOTE: Will not work on non-factory Glock mags.... BUT, with factory Glock mags? A must have. I have 4 total mags and bought the +2 for each. Rock solid. Stays put. Adds 2 rounds, increases hand grip.... Dislikes..? Zero. Buy it. You will love it.

    The best!

    I recently acquired a 42 and didn't understand why someone wouldn't just get a revolver if it can only hold 6. Also if you are a man then your pinky likely has no where to go... solved! Fired about 350rds no problems at all

    Exactly what I was looking for!

    I ordered two. Installing them took about two minutes. Now I can carry 16 (+1) rounds and it feels like a whole different gun. I've put about 50 rounds through it and had no issues with feeding.

    Great addition to the Glock 42

    Posted by Jim on 31st Jan 2022

    Bought these for my wife because she has little strength in her hands and without something for the pinkie finger to grip, you lose a lot of hand strength. These made a huge improvement in her grip and shooting accuracy; and the 2 extra rounds are just an added bonus.

    Great Mag. Extension

    Posted by Sgt. P on 31st Jan 2022

    Have purchased many of these for G42 and G43. Function flawless and add additional capacity. Also, the mag extension gives me a very comfortable full grip on the slim line frame. As expected with no issues. Absolutely recommend this product.
