Kriss Super V System from TDI, Inc.

The G30 MagEx 17-Round Extension is the World’s First Extension Kit
That Extends the Glock 21 Magazine to a Full 30-Rounds

Transformational Defense Industries, Inc. (TDI) formally aligned themselves with MagPul Industries Inc. in November 2005 with a design and engineering services contract. Their original agreement was in place to help support the KRISS design team.  Since that time, their relationship has evolved to the point where MagPul is now a major contributor to the KRISS line of accessories. Among the KRISS accessories MagPul produces, the KRISS Super V G30 MagEx 17-round extension to the Glock 21 13-round magazine perfectly exemplifies the nature of that relationship.

"We felt it was necessary to custom-design a 30-round Glock 21 magazine extension in order to provide for the tactical needs of our MIL and LE customers and for shooting enjoyment of our CIV shooters" said Chuck Kushell, CEO of TDI. "With MagPul Industries' experience in producing superior magazines, we knew they were the best fit to produce a 17-round extension to the Glock 21 13-round magazine for our KRISS .45 ACP family firearms as well as for the owners of Glock 21's."

The KRISS G30 MagEx is custom-designed and built to exacting KRISS-TDI standards by MagPul Industries, Inc. in the USA exclusively for the KRISS .45 ACP family firearms. The KRISS MagEx G30 "+17" design quickly converts the Glock 21 13-round magazine to a full 30 rounds which assembles and easily with no special tools required. The magazine extension has an inner and outer sleeve of injection molded high-performance, fiber-filled polyamide (PA) composite material for strength, toughness and dimensional stability. The magazine extension also contains an ISMI premium spring, manufactured exclusively with certified aerospace specification alloys.  The product uses standard Glock 21 13-round .45 ACP magazine components - magazine body, follower and base plate and is designed to fit BOTH the KRISS family of firearms and the Glock 21. The KRISS G30 MagEx is compatible with all KRISS Super V system .45 ACP firearms (SMG, CRB/SO) and with Glock 21 .45 ACP pistols.

To help load your 13 or 30-round Glock 21 magazines faster, TDI also offers a KRISS Vector Speed Loader. The KRISS Uplula™ universal multi-caliber speed loader works on virtually every type of single and doublestack magazine.
