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.

Note: Requires user assembly onto your existing G21 magazine bodies (magazines sold separately).
