This is an extremely scarce Astra Factory made extended 20 round magazine for the Astra 300 pistol. They are pictured in the pre war Astra catalogs and could be had in 15 or 20 rounds. They are pictured in Len Antares excellent Astra book. This is the only one that we have ever come across and I do not think that there are many in the states or anywhere for that matter as only a few were ever made. If you are a serious Astra Collector this will be something that you will definitely want. Normally we would just dump this in the mag section with no fanfare but this is such a rare and unique item we wanted to make sure the right person knows about it. We probably have it priced way too cheap.
