Ets Mag Sig P320 Extnd 9mm 40rd Clr

The ETS Mag Sig P320 Extended 9mm 40-round clear magazine delivers maximum ammunition capacity for the Sig Sauer P320 platform. Built from advanced polymer materials, this extended magazine provides the round count needed for serious training, duty applications, and competitive shooting without sacrificing the reliability operators depend on in the field.

Elite Tactical Systems Group engineered this 40-round magazine with extreme impact resistance—the polymer composition resists cracking and breaking even when dropped or subjected to rough handling. The construction maintains dimensional stability indefinitely, even when fully loaded for extended periods, eliminating feed lip creep and body spread that degrades older magazine designs. Temperature tolerances remain stable across harsh environments, chemicals, and cold exposure without brittleness. Precise manufacturing ensures consistent feeding and seating reliability across thousands of cycles.

This extended-capacity magazine suits shooters running P320 systems who need higher round counts for training blocks, duty belt loadouts, or competition stages. The transparent construction allows rapid visual verification of ammunition status without removing the magazine, a practical advantage during transitions between shooting positions. At 13 inches in overall length, the extended profile requires holster and carry consideration but delivers genuine capacity advantage for shooters prioritizing ammunition volume over concealability.

Polymer magazines dominate modern duty and competition environments because they eliminate the corrosion, weight, and maintenance demands of steel. The 40-round capacity positions this magazine at the higher end of practical extended options for the 9mm platform—balancing round count with controllable ergonomics and reload dynamics that serious P320 operators require.
