Specifications come from the source cited alongside them; counts are based on our catalog as of the date stated. Not legal advice: what follows from these figures in a given country is decided by that country’s law. Waffenschrank is not affiliated with the manufacturers named.

Magazines that fit

Magazines that fit this model according to their manufacturer — with capacity, caliber and the limits by country in the accessories catalog.

United States (federal law): Federal law sets no capacity limit for magazines; the former limit expired in 2004 and has been repealed (18 U.S.C. § 922(w) (repealed)). Several states do limit capacity, however – for example California, New York, Connecticut, Maryland, Washington and Colorado – some as a sales ban, some as a possession ban. This list is not complete; the law of the state decides.
