The Check-Mate 1911 .45 ACP 7-Round GI Magazine is an ultrareliable 1911 magazine, specifically designed for tactical and competition pistol applications. Designed around a corrosion-resistant blued steel tube for exceptional durability, while 360° polishing eliminates friction and drag for lightning-fast operation. Better yet, this magazine features a standard 7-round steel wire spring and dimpled GI follower for improved reliability, while the GI-style feed lips deliver a snug fit and reliable feeding and function with every round. Plus, the flush-fit base plate delivers snag-free carry and draw, while simultaneously protecting the magazine tube and spring from unintentional damages due to drops, bumps, and more. Made in USA.
