Sportsmansguide.com has mags for Beretta 96 20 round. They can also be used in the CX4 storm that uses 96 mags. Last week they had 3 packs for around $60. I bought them a while back for my Beretta 96 and that is what led me to buy the 40 cal instead of the 45. the mags are interchangeable and I already had the extra hi cap mags. anyway that work great in the storm. Thought some might be interested , because everyone has been looking for hi cap for the 40. Make sure your storm can use the beretta 96 mags. It is my understanding that some storm accept these mags and others accept another type.
