The Mec-Gar MGCG4508SPF delivers enhanced feeding reliability and extended service life for 1911 Government pistols chambered in 45 ACP. This 8-round magazine addresses common feeding issues found in factory magazines while maintaining the classic profile shooters expect. Precision manufacturing and premium materials ensure consistent performance across thousands of rounds.
What Makes This Different
Mec-Gar's advanced spring technology and follower geometry create smoother feeding compared to standard GI magazines. The stainless steel construction resists corrosion in humid conditions where blued magazines typically fail. Heat-treated components maintain tension longer than conventional springs, reducing the need for frequent replacements.
