Esstac has been busy churning out new handgun magazine pouches including options for the Glock 43X, Sig P365, and 40° Angled Single Pistol KYWI. These feature the same KYWI construction that you know and love with a Cordura outer pouch with an internal tensioner.
The G43X and Sig P365 pouches are identical. It fits G43X magazine, Shield Arms S15 magazines, and P365 magazines. There is a gap between the pouches that makes grabbing a single magazine a bit easier. These pouches are intended for belt use (not recommended for use on PALS webbing).
The 40° Angled Single Pistol KYWI is built like the standard Single Pistol KYWI with the addition of a section of One-Wrap that allows the pouch to be belt mounted at an angle. It is available with either the standard double-stack magazine insert or an insert specifically for 2011 magazines.
