re Kel-Tec Sub 2000 machined for SW59 magazines. I got mine with 2 mags by Mec-Gar. The Mec-Gars work fine in my SW59 pistol. However the SW59 mags mfgd by S&W which came with the pistol do not work in the KTS2000. The reason is that the Mec-Gars clip-lock-aperture is rectangular 4mm hi by 7.5 mm wide while the SW59 are rounded on the trailing edge and 3 mm hi by 7mm wide. The clip retention piece on the KTS2000 is a perfect fit for the Mec-Gars, making it too big to latch the SW59 mags. HAS NO ONE ELSE NOTICED THIS?
