Abstract
A magazine entrance guide integral with the mainspring housing of the firearm is provided. It is a guide having four sloped surfaces front, back and two opposite sides guiding double column staggered round high capacity magazine entrance during insertions. The magazine entrance guide with widely spaced sides in one embodiment has upwardly extended opposite side stabilizing extensions enclosing opposite sides of the gun butt within opposite side grip plates that counter torsion forces between the guide and the mainspring housing. In another embodiment opposite side stabilizing extensions are positioned within the angled out opening sides of the gun butt magazine opening to counter torsion forces between the guide and the mainspring housing.
