These 3 round mags are not the cheap imitations but high quality mags, matched and machined to fit the M-11 or M12 .380 with Larger Mag well. The feed lips are a bit narrower and shorter to hold the .380 rounds. Also, if you are looking for the perfect pouches to carry these for competition or just shooting, our SMG pouches are a perfect fit for these magazines. Fits SWD models only.These mags are larger than the smaller .380 mags. Please see 3rd & 4th photo of our 30 Round Magazine for M-11A1 .380 ACP for mag size measurements.
