So I wasn't able to find any original 10 rd. fixed mags but after just a bit more research I came across hitech mags with either come as detachable or fixed. They have a lifetime, "no jam and no fitting issue" warranty. They are a bit pricey but that's becoming the norm and at least this comes with a warranty.
