The Armscor 9mm 124gr FMJ serves primarily as a training round, with performance characteristics that make it particularly suitable for extended practice sessions. At 1090 fps, this ammunition generates 348 ft-lbs of muzzle energy through its mid-weight 124-grain projectile. These specifications place it squarely in the range of standard pressure 9mm loads, making it compatible with both full-size and compact pistols.

For practical training applications, this load's moderate velocity contributes to manageable recoil characteristics that benefit skill development. The 124-grain bullet weight matches common defensive loads, allowing shooters to maintain consistent sight pictures and follow-through techniques that translate directly to defensive shooting scenarios. This weight class tends to cycle reliably in most 9mm pistols, including older models with traditional recoil spring rates.

This ammunition particularly excels in dynamic training environments, from basic marksmanship practice to more advanced tactical drills. The full metal jacket design maintains consistent feeding in high-round-count sessions, while the standard pressure loading reduces wear on pistol components during intensive training. For shooters focusing on practical accuracy development or action shooting sports, these rounds provide the consistent point of impact needed for building fundamentals without excessive barrel fouling or erratic performance.
