I just traded up a Llama .45 MiniMaxII. From my reading there are dimensional differences between some 1911 parts and the Llama. For instance the mag release is different, looks same but is larger. Also the safety is different. I understand the 1911 fire control parts can be fitted. As for mine, it is needing some smithing. That sorry plastic plunger tube is going to be replaced! I have already worked the trigger, sear, and am now working on getting the safety to shift positions without two hands.
