I think he's lookin for a magazine release, not a magazine. You might look at
www.e-gunparts.com since LLama went under parts have been far and few between. A friend had a llama 1911 in 40 S&W he ended up selling it because parts were very hard to come by. something else you may try is see if a gunsmith can modify a traditional 1911 mag release. those LLamas are different but similar in many aspects to traditional 1911's so modifying parts shouldnt be too hard. good luck
