PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

What it does
This kit replaces the factory magazine base setup with an extended baseplate, outer sleeve, and extended spring to increase total 9mm capacity to 40 rounds when installed on a compatible Glock 17 magazine body.
Why it’s worth it
For KRISS Vector owners, Glock mag PCC shooters, or range-day buyers who want more capacity without buying a complete extended magazine, this kit makes sense. It is not complicated gear—it does one job: more rounds in the mag, less time feeding the tiny brass dragon.
