Looking on Hatsan's website they don't list what magazines are compatible, they have a product page that shows pictures https://escortshotgunsusa.com/product/box-magazines/ But there is no item number, or link to buy, or even any info on compatible other brands. I found a couple on atlanticfirearms.com that look similar, but I can't t say for sure they'd fit or function https://atlanticfirearms.com/products/ifc-magazine-13-round-410-2-5-for-ifc-410-upper-receivers-410mag13 ------------- Id contact HatsanUSA, Inc. P.O. Box 576 Bentonville, AR 72712 Phone: 1.877.278.4448 Or buy using the "contact us" form on their website https://escortshotgunsusa.com/contact-us/
