Glock 17 Magazine Extension – MagEx2 +23 Round – 9mm – Black 3-Pack
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The KRISS USA MagEx2 Black 3-Pack gives you three +23 round 9mm magazine extension kits for standard Glock 17-pattern magazines. Each kit converts a compatible Glock 17 magazine body to a 40-round total-capacity setup for KRISS Vector 9mm firearms, Glock handguns, and Glock-magazine-compatible PCC builds.
This is the better buy for setting up multiple magazines at once. One extended mag is useful. Three means less reloading, fewer excuses, and more time actually shooting.
Fitment
- Fits standard Glock 17-pattern 9mm magazines.
- Designed for KRISS Vector 9mm use with compatible Glock 17 magazines.
- Works with Glock handguns and Glock-magazine-compatible 9mm PCC setups that accept standard Glock 17 magazines.
- Each kit adds +23 rounds.
- Total capacity per compatible magazine: 40 rounds.
Does NOT fit
- Does not include Glock magazine bodies.
- Does not fit every Glock magazine.
- Does not fit 10mm or .45 ACP magazines. This card is for the 9mm version only.
- Does not bypass state magazine-capacity laws.
What it does
Each MagEx2 kit converts one compatible Glock 17-pattern 9mm magazine into a 40-round extended magazine setup using an extended baseplate, outer sleeve, and extended spring.
Why it’s worth it
The 3-pack is the smarter setup for KRISS Vector owners and PCC shooters building out multiple mags. It keeps your gear consistent, gives better value than buying singles one at a time, and makes range days smoother because reloading every five minutes gets old fast.
