KRISS USA 45 ACP +17 Rounds Glock 21 Magazine Extension - FDE (3 Pack) - KVA-MX2K45FD01 - 811607032932

Product Description

Standard 13-round factory Glock 21 magazines limit round capacity during sustained competition stages, tactical training exercises, and PCC defense staging. For shooters running the KRISS Vector or Glock-pattern .45 ACP carbines, frequent reloads slow down splits and compromise firepower density. The KRISS USA Mag-Ex2 .45 ACP +17 Magazine Extension Kit 3-Pack in Flat Dark Earth (KVA-MX2K45FD01) solves payload limitations by adding 17 additional rounds to standard G21 factory magazines, converting them into massive 30-round high-capacity feeding systems.

Constructed from heavy-duty composite polymer materials finished in earth-tone Flat Dark Earth (FDE), the Mag-Ex2 outer sleeve extension integrates seamlessly with factory Glock 21 magazine bodies. Each kit includes a custom extra-long high-tensile steel drive spring designed to maintain optimal upward pressure on heavy .45 ACP cartridges, ensuring positive lock-up and flawless feeding from the first round to the last.

Engineered primarily for the KRISS Vector .45 ACP platform, these extended magazine adapters are fully compatible with standard factory 13-round Glock 21 magazine bodies across all generations. Supplied in a cost-effective 3-pack, the KVA-MX2K45FD01 kit provides maximum ammunition volume, reduced reload downtime, and high-impact tactical staging durability.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment & Compatibility Matrix: Requires factory OEM Glock 21 13-Round .45 ACP Magazines (Glock factory steel-lined polymer magazine bodies). Compatible with KRISS Vector .45 ACP firearms, Glock 21/30 handguns, and .45 ACP PCC platforms using G21 magwells. Note: Requires user assembly onto your existing G21 magazine bodies (magazines sold separately).

Assembly & Conversion Sequence:

  1. Safety check the host firearm and ensure factory Glock 21 magazines are completely unloaded.
  2. Depress the locking insert pin on the OEM Glock 21 baseplate and slide the factory floorplate and spring off the magazine body.
  3. Discard the factory spring, floorplate, and insert (retain the OEM follower).
  4. Insert the extended KRISS Mag-Ex2 high-tensile spring and original Glock follower into the G21 magazine tube.
  5. Slide the Mag-Ex2 FDE extension sleeve over the base of the magazine body until fully locked into place by the baseplate retainer cap.
