The CMC Products MRP9FS10 Range Pro magazine transforms any full-size 1911 into a reliable 9mm platform with enhanced capacity and consistent feeding. This precision-engineered magazine addresses common feeding issues found in standard 1911 conversions while delivering the extended capacity competitive shooters demand.

What Makes This Different

Unlike basic conversion magazines that often struggle with reliable feeding, the Range Pro features CMC's proprietary follower design and spring tension calibrated specifically for 9mm cartridges. The stainless steel construction resists corrosion while maintaining dimensional stability under repeated use. Independent testing shows 99.8% feeding reliability across multiple ammunition weights, significantly outperforming standard conversion magazines that typically achieve 85-90% reliability rates.

Key Features

  • 10+1 capacity extends shooting sessions without frequent reloading
  • Stainless steel body with black fluoropolymer base plate for durability
  • Precision-machined follower eliminates nose-diving and double-feeds
  • Compatible with all full-size 1911 frames chambered in 9mm
  • Heat-treated spring maintains consistent tension through 5,000+ cycles
  • Witness holes allow quick round count verification
  • Drop-free design ensures reliable tactical reloads
Competitive shooters report consistent cycling through USPSA matches without feeding interruptions, while law enforcement agencies note the magazine's performance in adverse conditions including sand, mud, and temperature extremes from -10°F to 140°F. The extended capacity reduces reload frequency during qualification courses and training scenarios. Range testing with various 9mm loads from 115-grain to 147-grain shows uniform feeding geometry across the entire weight spectrum.
