Product Description
The KRISS USA .45 ACP +17 Round Magazine Extension 3-Pack (KVA-MX2K45BL01) is a high-capacity magazine conversion kit engineered to expand standard Glock 21 factory magazines for optimal performance in the KRISS Vector .45 ACP carbine and SDP platforms. By converting standard 13-round Glock 21 magazines into massive 30-round extended stick magazines, this 3-pack kit delivers maximum firepower and sustained strings of fire without frequent reload interruptions.
Constructed from high-impact composite polymers with a durable matte black finish, the extension housing sleeve matches the aggressive aesthetic geometry of the KRISS Vector receiver. Each adapter kit includes an extended base housing, a outer sleeve extension, and an extra-long, high-tensile steel power spring calibrated to deliver reliable, uniform follower pressure down to the last round.
Packaged conveniently as a 3-pack, the KVA-MX2K45BL01 kit is an indispensable upgrade for competition shooters, home defense staging, and high-volume range training with the KRISS Vector .45 ACP system.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Designed to attach to factory OEM Glock 21 .45 ACP 13-round magazines for use in KRISS Vector .45 ACP platforms and Glock 21 handguns. (Not compatible with aftermarket non-OEM Glock magazines or .40 S&W/9mm variants).
- Perform a complete firearm safety check: drop the magazine, lock the bolt/slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Depress the side insert retaining tabs on a factory Glock 21 magazine to remove the stock baseplate, insert plate, and factory spring.
- Clean all factory lubricants, debris, and carbon from the interior polymer walls of the Glock magazine body.
- Insert the extended KRISS power spring into the magazine tube, ensuring correct follower orientation at the top.
- Slide the KRISS extension body sleeve onto the magazine body rails until the locking bottom cap snaps securely into place.
- Load magazine to full 30-round capacity and manually cycle dummy rounds to confirm feed-ramp lockup and slide/bolt catch function.
