Tang talks about the basics of Hi-Capa airsoft pistols in Fox Airsoft's "Know Your GBB" series... "What is a Hi-Capa? The name itself originates from a TM design but it is a fictitious model name that takes after the real life 2011-style pistol. The 2011 is popular in the real gun world in the competition scene and is highly customized. The airsoft gun takes after that and is favored due to its huge aftermarket parts support and upgrade potential.

TM is known for being the originator of airsoft guns in Japan. Though currently around and still kicking, they don't make anything for the global market and players have found that they have to import these airsoft guns to enjoy a really good and customizable pistol.
Likewise all of our AEGs are descended from TM designs. With that comes many brands who make a clone of this pistol, some good, some bad. Today we're going to showcase pistols from Echo1/JAG Arms which I am happy to report fall in the good category for Hi Capa clones. You get all the aftermarket support and parts compatibility along with tremendous value and performance out of the box."
