Yes, any of the Government/Commander size grips will fit.
Most likely not, most Llama pistols are not standard 1911 pistols. However if yours does use standard grip screw spacing, this will work.
Any of the models listed for 1911 Government should fit your gun.
Yes, any of the models marked for "1911 Officer" will work for that gun.
No, these will not fit double-stack models. These will only fit traditional single-stack models.
No, the Browning 1911-380 is not a full size 1911, so these will not fit.
Per Hogue, yes these will accommodate ambidextrous safety model 1911's however the rubber laser grip models may require removing a minor amount of material.
