TF Magazine Extension for Glock 41+1

RIDICULOUS CAPACITY!

Add our +12 extension kit to your Glock 31-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.

.40 owners can use the same kit on a 22-round .40 mag, achieving 30+1! (We need to send you the correct extension, so be sure to tell us whether you're shooting 9mm or .40/.357 Sig.) Magazine body not included.

Not shipped to CA.
