Product Description
RIDICULOUS CAPACITY!
Add our extension kit to your Glock 31/33-round magazine and transform it into a giggle-worthy 41+1 round BIG stick.
This is the same extension as our well-known 170mm +12 but it ships with a crazy-long machine-pistol spring. Normally we use Delrin for Glock mags, but we did these up in a beautiful polished aluminum. Magazine body not included. Due to U.S. State Department restrictions, we cannot ship this part internationally.
NOTE: Because of a combination of factors, we build our basepads slightly "short" for best reliability. As a result, they will run properly with ammunition loaded to 1.125" overall or less. That's a typical length for 115- and 124-grain loads, but some (notably, Winchester 115 RN) will go out all the way to 1.160".
HINT: If your extension will take 35 rounds and then becomes unreliable (or sticks), check the length of your ammunition! Question? Give us a call and we can explain.
