STI 1911 Officer Magazine

STI 1911 Officer magazines are made specifically for STI's popular line of 1911 pistols with officer model grips such as the Duty One, Escort, Guardian, and Off Duty.  They also work well in any other 1911-style pistol with officer model grip.  The design of the magazine positions the rounds high in the tube to promote reliable feeding.  The 9mm magazine holds approximately 7 plus 1 rounds and the 45 ACP magazine holds about 6 plus 1 rounds.
